Wrong behaviour of PSALM inside docker

[bdovaz]

Describe the bug

If I run it locally, it works correctly but through Megalinter it only works if I don't ignore the vendor folder.

To Reproduce

1. Run the test_local.ps1 script and check that there are no issues.
2. Execute the script test_docker.ps1 and check that there are errors.
3. Open the .mega-linter.yml file and comment the FILTER_REGEX_EXCLUDE line.
4. Execute the script test_docker.ps1 and check that there are no issues.

I obviously don't want to analyze the scripts in the vendor folder (they are from third party libraries) but I do want to include them with the psalm.xml file so that it resolves the dependencies of my code correctly.
