Fix and reformat javadoc author tag

[axmmisaka]

See #1477 for more context, the questions are:

1. Do we want to keep e-mail or only keep name, effectively eliminating the problem?
2. Do we use {@literal } or < >?
3. Why are emails not showing in the generated Javadoc
4. Why is javadoc build failing

[cmnrd]

I think using {@literal } is a great solution. How does this look in the generated rendered html?

[lhstrh]

The description of the PR seems to suggest that JavaDoc generation is broken?

[axmmisaka]

Yeah, doesn't appear to be working as I can't find @author tags in generated HTML plus ./gradlew javadoc is spitting out tons of errors on java files in src-gen

[axmmisaka]

./gradlew javadoc doesn't produce javadoc with author tag (and generate docs for files under src-gen which doesn't appear to be right) so I can't test this locally, and my intellij generate javadoc is not working, F

Now every and all author tag will be like

/**
* @author Hitori "Bocchi" Gotō
*/

[cmnrd]

This looks great! Thanks!

I think we should merge this. However, this also means we need to manually integrate the changes into #1482... @a-sr What do you think?

[a-sr]

I agree. You can merge this. There are already some other conflicts in #1482 that need to be resolved manually. A few more will not change much.
