fix: tags in git-cli commit mode

[h3rmanj]

closes #465

Fixes both cases described in the issue:

• Custom publish script that does not create tag errors

  This case happens when you have a custom release script, instead of running changeset tag or changeset version, that does not create tags locally, but only prints New version: to force changeset to still create a release (which would implicitly create a tag as well). Not sure how they ended up with that solution though, maybe it predates the changeset tag command?

  Fixed by passing ignoreReturnCode: true when pushing the tag. Not sure if this can have some pitfalls if an error is returned for other reasons though.

• createGithubReleases: false does not push tags

  In Introduce an option to use the GitHub API to commit changes, for GPG #391, pushing tags was moved from always happening, to only happening if createGithubReleases is true. https://github.com/changesets/action/pull/391/files#diff-69c9100f2a3041c22e8fddf77d13fd7eb1aa42a8a200aa35a81ea589c135e66aL133

  Fixed by moving the createGithubReleases if-statement to only affect actually creating a github release.
