Build: Backport changelog generation from jQuery

[mgol]

For some reason, read -p doesn't work in the pre-release.sh script - or at least that's my hypothesis why the script gets stuck on pre-release. I thought since Code is using it in post-release.sh, it should also work in pre-release.sh, but maybe not?

Hopefully, now it'll work. My previous testing was limited as dry-run doesn't show all these issues, so I merged the release-it PR and I tried to release an alpha for testing; that's when I hit the issue.

Backport the changelog generation script from jQuery Core. Rename the old CHANGELOG.md to LEGACY_CHANGELOG.md to not lose it, but I'm contemplating moving it to GitHub Releases. Move current CHANGELOG.md entries to GitHub Releases.

I think I prefer posting the generated changelog to github release notes. Do you agree?

Yeah, that would be more similar to other projects; I just wander what to do with the legacy changelog entries. Should I just create releases on GitHub for them all and then drop the legacy changelog?

[timmywil]

I think you could just leave it for historical purposes and add a note to the top that says all release notes since are in GitHub releases.

[mgol]

Cool, so are there any code changes needed beyond the note at the top? Keeping the changelog.md file in the repository with the changelog for the last release is what jQuery does as well right now.

[timmywil]

I guess not.

@timmywil I went ahead and copied all info from the old changelog to GitHub Releases: https://github.com/jquery/jquery-mousewheel/releases. This repo only has data for version 3.0.0 & up as previous ones were apparently not on Git so I posted all changelog entries up until 3.0.3 in a single entry; newer ones all have separate entries.

I removed the legacy changelog from this PR. PTAL.
