Address quoting issue impacting dev_paths containing @ symbols (#48555)

* Address quoting issue that casuses dev_paths containing @ symbols to parse as versions

* Fix additional location were dev_path was imporperly constructed

The dev_path must be quoted to avoid parsing issues when
paths contain '@' symbols. Also add tests to catch
regression of this behavior

* Format to fix line length

* fix failing tests

* Fix whitespace error

* Add binary_compatibility fixture to test

* Change string formatting to avoid multiline f string

* Update lib/spack/spack/test/concretization/core.py

* Add tmate debug session

* Revert "Add tmate debug session"

This reverts commit 24e2f77e3c.

* Move test and refactor to use env methods

* Update lib/spack/spack/test/cmd/develop.py
