Address GitHub Actions warnings

[VKTB]

This PR will close #397

Description

• Addresses the warnings by GitHub Actions in the ci-build.yml and release-build.yml workflows
• Updates and pins actions to commit SHAs in the ci-build.yml and release-build.yml workflows
• Configures Dependabot to check and open new PRs when new action versions are released

I am not sure how the relekang/python-semantic-release Action works but it's currently pinned to master and we should not do this. When I search for this action in Google, I get results for python-semantic-release. Are they the same? If they are then I am guessing we can update the usage of relekang/python-semantic-release@master in release-build.yml to python-semantic-release/python-semantic-release@bfa503c3ef98d240a6d9cb09a8a8603e84200b42 # v7.33.2.

@VKTB It looks like relekang/python-semantic-release redirects to https://github.com/python-semantic-release/python-semantic-release so I'd go ahead and make that change

Addressed this so it is now ready for review.

If the Python semantic release doesn't work as expected, let me know and we can have a look at it together
