damcav35 be33848d81 Damcava35/set version (#257)
* feat: add "--set-version" option

This feature will allow to chose a specific cis version to run, like debian 11 or debian 12

* chore: configure current repository as a version

And use it as default version.

To this end, the scripts in bin/hardening have been made generic by removing the associated recommendation number.
Only impact is if you are used to execute scripts directly from bin/hardening.
In this case, please use the "bin/hardening.sh" wrapper as intended.

I had to rename 2.3.1_disable_nis.sh to uninstall_nis.sh, as it was conflicting with 2.3.1_disable_nis.sh

Also, there was a doublon between 1.1.1.8_disable_cramfs.sh and 99.1.1.1_disable_cramfs.sh ; the former was kept

* chore: remove CIS recommendation numbers from bin/hardening scripts

* fix: some tests are failing

find_ungrouped_files.sh and find_unowned_files.sh tests can not be executed multiple times:
- test repository is not cleaned
- configuration is updated multiple times

Those tests are also failing, because:
- the sed to change the status in the configuration was also changing the test folder path.
- missing /proc in EXCLUDED paths
- the EXCLUDED configuration doesn't have the correct format for egrep
