CI: Update peter-evans/create-pull-request to v7.0.2

We're currently using peter-evans/create-pull-request v6.0.0 which has a known issue that affects our services-validator action when attempting to update an existing PR. This issue was fixed in v6.0.1, but we can update to v7.0.2.

CI: Update softprops/action-gh-release to v2.0.8

https://github.com/softprops/action-gh-release/compare/9d7c94cfd0a1f3ed45544c887983e9fa900f0564..c062e08bd532815e2082a85e87e3ef29c3e6d191

Motivation and Context

Keep third-party actions somewhat up to date.

Primarily, this is to fix an issue where the peter-evans/create-pull-request action tries to update an existing PR. However, I also noticed softprops/action-gh-release had some updates, and the changes seemed trivial.

How Has This Been Tested?

It hasn't.

I'm currently working on a larger CI update PR which would have included these two as well.
