Updates to CI build-test-release pipeline

[a-larkins99]

Jenkinsfile changes:

• Update to use PACE-shared-lib for setting of github status following pull request;
• Parameterize the pipeline to allow adjusting of python and Matlab version when manually running;
• Update to use rocky8 and icdpacewin;
• Update to use conda environments throughout to keep consistent between Windows and Linux;
• Remove usage of podman due to this no longer working;
• Introduce separate build installer stage;
• Remove unused external PowerShell and bash scripts;

Github actions workflow changes:

• upload_pypi.yml updated to remove unnecessary stage as release.py is able to upload to pypi.

Misc file changes:

• Add MCR_license.txt
• Update 'ApplicationName' of installer in make_package.m to result in a better named installer dir (Pace_Python_Installerinstaller -> pace_python_installer);
• Adjust paceneutrons\_init\\.py to account for varying dir structure when determining matlab version from ctf file. This changes depending on if done during use or during release stage of Jenkins pipeline. Paths are updated to account for this where used, including in release.py;
• Regex in release.py changed to properly detect description from changelog when the tag includes letters e.g. 0.3.0a0.

Notes:

• Brille test in run_test.py disabled because hang on Linux (see #28) causes CI job to fail.

@mducle following the changes to fix the pace_neutrons command, the CI fails with the following error:

error in pace_neutrons setup command: "values of 'package_data' dict" must be a list of strings (got 'MCR_license.txt')

Ooops... sorry it was because the MCR_license.txt file was not being copied into the wheel... I didn't check the building of the wheel sorry. Could you change that line to:

    package_data={'pace_neutrons':CTFFILES, 'pace_neutrons':['MCR_license.txt']},

(e.g. make it a 1-element list).

I think all the required changes on this one are done now, unless you'd like the env bit changed to printenv?
