[NEW CHECK] version check for testing-actions

[mcm1957]

I'm sure that

• This issue does not report a false-positive detection (use dedicated template for this)
• This issue does not request a change or removal of existing check (use dedicated template for this)
• There is no other (open) issue with the same topic (use the search!)

Description of check to be added

The version of testinga ctions should be checked.

If a dedicated version ( not @v1, @v2 but v2.0 or v2.0.0 is specified) log a suggestion that only major version should be locked in

If specified version is lower than current version log a warning suggesting an update.
