Fix ArgumentError Malformed version number in github actions

[amazimbe]

What are you trying to accomplish?

Reduce the number of malformed version errors in Sentry for github actions ecosystem.
Fix issue: https://github.com/github/dependabot-updates/issues/6446

More than 8k occurrences of this issue in Sentry and a large proportion of these were in the github actions ecosystem.

Within github actions, itself, there are also multiple use cases that lead to this issue. The fix in this PR is for the use cases where we create a security update PR (https://github.com/dependabot/dependabot-core/blob/main/updater/lib/dependabot/updater/operations/create_security_update_pull_request.rb#L98) or a group update PR: https://github.com/dependabot/dependabot-core/blob/main/updater/lib/dependabot/updater/operations/create_group_update_pull_request.rb#L61

Variations of this issue:
https://github.com/github/dependabot-updates/issues/6446

How will you know you've accomplished your goal?

Once this has been deployed. I expect zero occurrences of this issue from these use cases. This can be monitored in sentry.
