Shorter options help

[Gedochao]

Fixes #1669

• bump scala-cli-signing and case-app
• only show tags.important or tags.must help options in the short help (sub-command --help)
• example output:

$ scala-cli fmt -h
Usage: scala-cli fmt [options]
Formats Scala code.

You are currently viewing the basic help for the fmt sub-command. You can view the full help by running: 
   scala-cli fmt --help-full
For detailed documentation refer to our website: https://scala-cli.virtuslab.org/docs/commands/fmt

Format options:
  --check                                     Check if sources are well formatted
  --save-scalafmt-conf                        Saves .scalafmt.conf file if it was created or overwritten
  -F, --scalafmt-arg string*                  Pass an argument to scalafmt.
  --scalafmt-conf, --scalafmt-config string?  Custom path to the scalafmt configuration file.
  --dialect, --scalafmt-dialect string?       Pass a global dialect for scalafmt. This overrides whatever value is configured in the .scalafmt.conf file or inferred based on Scala version used.
  --fmt-version, --scalafmt-version string?   Pass scalafmt version before running it (3.6.1 by default). If passed, this overrides whatever value is configured in the .scalafmt.conf file.

Help options:
  --help-js                                      Show options for ScalaJS
  --help-native                                  Show options for ScalaNative
  --help-doc, --doc-help, --help-scaladoc, --scaladoc-help  Show options for Scaladoc
  --help-repl, --repl-help                       Show options for Scala REPL
  --help-fmt, --fmt-help, --help-scalafmt, --scalafmt-help  Show options for Scalafmt

Btw. as a side effect of these changes, I had to adjust the behaviour of --help-js and --help-native as well.
Previously, they simply ran the default --help with Scala.js or Scala Native options' sections included (alongside others).
Now, I instead run --help-full for just those help options groups.

old output:

▶ scala-cli --help-native
Usage: default [options]

Scala options:
  --js                                           Enable Scala.js. To show more options for Scala.js pass `--help-js`
  --native                                       Enable Scala Native. To show more options for Scala Native pass `--help-native`
  -P, --plugin, --compiler-plugin string*        Add compiler plugin dependencies
  -O, --scala-opt, --scala-option, --scalac-option option  Add a `scalac` option. Note that options starting with `-g`, `-language`, `-opt`, `-P`, `-target`, `-V`, `-W`, `-X`, and `-Y` are assumed to be Scala compiler options and don't require to be passed after `-O` or `--scalac-option`.

  --scalac-help, --help-scalac                   Show help for scalac. This is an alias for --scalac-option -help
  --scalac-verbose, --verbose-scalac             Turn verbosity on for scalac. This is an alias for --scalac-option -verbose

  --execute-java string*                         A synonym to --scala-snippet, which defaults the sub-command to `run` when no sub-command is passed explicitly
  -cp, --jar, --jars, --class, --classes, -classpath, --classpath, --extra-jar, --extra-jars, --class-path, --extra-class, --extra-classes, --extra-class-path paths  Add extra JARs and compiled classes to the class path

case-app currently doesn't seem to support filtering out Other options, for example

Great work! I left a very minor comment for a future refactor
