Bug: PHPStorm URN catalog generated with absolute paths + inconsistent behavior

[lbajsarowicz]

Preconditions

1. Lack of consistency between Magento's dev:urn-catalog:generate and MFTFs generate:urn-catalog
2. Invalid path used for MFTF URN catalog

Steps to reproduce

1. Run vendor/bin/mftf generate:urn-catalog inside your Docker
2. Run PHPStorm and verify outcome

Expected result

1. You should be asked to provide path to .idea/misc.xml
2. Paths should be relative to the project

Actual result

1. You are asked to provide .idea directory path
2. Paths are absolute from inside Docker.
