Update github actions PR

Nothing really important, but felt like doing a minor contribution after ages 😄

• Update to use checkout v4 github action
• Use PHP matrix to perform static analysis & tests to PHP version 7.3, 7.4, 8.1, 8.2
• Add installable tools to php setup github action
• Add cache github action to save & load vendor packages from cache instead of re-installing
• Indentation to phpunit.xml.dist file

@aashwin-rvvup not sure if you had the chance to have a look at this?

Let me know if you want to do it against a different branch to allow for the pipelines to work

Hi Rou, thanks for your contribution I missed this PR previously. I have updated the base branch to a local one in this repo so we can check the pipelines. Ill take a look at this PR and get it in either today or Monday!
