feat: changelogs within npmx

[WilcoSp]

This pr will add the possibility to view the changelog.md & releases from a package's github (maybe others) repo within npmx.
This will make it easier to see the changelogs while not needed to leave npmx and allowing quicker access.

This pr is the first pr of #501

Currently this pr is in draft mode to allow for previewing while I still work on this pr.

i have good feedback! it works fine on https://npmxdev-git-fork-wilcosp-feat-changelog-1-npmx.vercel.app/package-changes/swarpc/v/0.19.0

its not really a "stress-test" per se (as I have a tool that manages the changelog for me, so it stritctly adheres to the KAC standard), but theres a few code blocks, strong-within-code tag once, etc. version splitting works fine, and the per-version outline menu is nice ^^

edit: uhhh as it turns out i also copy paste the changes in the github releases tab so its not really testing that oops

also, i have to admit that it took me quite some time to find the changelog button, i intuitively looked around the "Versions" section

i think it could be added either on each version or next to (while keeping it aligned but you get me) the community adoption button

yeah might be a nice idea to have as an extra button

i think it could be added either on each version or next to (while keeping it aligned but you get me) the community adoption button

This idea antfu also has in his pr #1368 and I do also think this would be very nice to have
