Running Megalinter v6.2.0 fails with ModuleNotFoundError: No module named 'megalinter.tests'

[chgl]

Describe the bug

Updating from 6.1.0 to 6.2.0 causes MegaLinter to fail with an exception when trying to run the semgrep linter.

I believe this was introduced via #1671, specifically https://github.com/oxsecurity/megalinter/pull/1671/files#diff-7e7ca1c29cf8191fada335419d7ecd0f342ef91b1c352e7bb76fd0de9995b4cdR9 - could it be that the modules under tests/ are not included in the container image?

Simply disabling semgrep via the following didn't seem to do the trick.

DISABLE_LINTERS:
  - REPOSITORY_SEMGREP

Also thank you for this great tool, I'm a huge fan of linters and static code analysis and use MegaLinter everywhere I can ❤️

@chgl this is now fixed in 6.2.1, please can you check again and confirm it's ok now ? :)

Works great now, thank you!

You're welcome, sorry for the bug ! (it was covered by test classes but for some strange reason the execution context was not the same )
