Add tool and image versions update function

[eileen-xue]

GitHub Actions will automatically check the tool versions on the 1st of January and July. It will update the tool and image versions and create a PR.

Action fails on step Create PR with error :

Create or update the pull request
  Attempting creation of pull request
  Error: GitHub Actions is not permitted to create or approve pull requests. - https://docs.github.com/rest/pulls/pulls#create-a-pull-request

Think we need to build in an access token?

[eileen-xue]

I think it is better to change the actions setting instead of switching the access token to a PAT. Using a PAT will show all actions using a personal account instead of a GitHub bot.

To update the actions permission

For this action to work you must explicitly allow GitHub Actions to create pull requests. This setting can be found in a repository's settings under Actions > General > Workflow permissions.

For repositories belonging to an organization, this setting can be managed by admins in organization settings under Actions > General > Workflow permissions.
