Update changesets' auto-commit feature to not suppress CI on commits (#…

…2052)

## Summary:

I recently updated our Changesets config to auto-commit the `.md` file when using `yarn changset` to describe a set of changes. This broke our releases as the default behaviour is that Changesets adds `[skip ci]` to the commit created when running `yarn changesets version`. No CI on that PR/commit, meant that none of our release Github Actions ran!

So this PR fixes the config so that Changesets no longer adds `[skip ci]` to any commits, but still auto-commits them.
