Add CLI option not to prepend v to versions

[MrVauxs]

As title says, preferably in the CLI. It is quite annoying to an otherwise excellent npm script to just run at the end of everything.

This seems to be the offending code.

keep-a-changelog/src/Changelog.ts

Line 89 in 79d06e7

return `v${release.version}`;

It's a good practice to prepend the git tags of the releases with v.
Anyway, there's already a tagNameBuilder option to customize the tag name.

A practice, but not a semver version. And if something relies on tags as the version then it'll break with the pretended v.

Anyway, there's already a tagNameBuilder option to customize the tag name.

TagNameBuilder is only available if you build a JS script. For such a small change in functionality I'd rather not have to create an entire script file for it.

Okay, but instead of creating a new option in the Changelog class, I think it's better to simply provide a cli option to use a different tagNameBuilder. For example:

changelog --no-v-prefix

I have modified the related PR with the suggestion.

Merged. Thanks!

I can't publish the NPM package due this bug denoland/dnt#421
