Workflow Tweaks - Removing Separate CS-Fixer

[lrljoe]

Run-Tests now runs in the following order

• First run PHP CS Fixer
• Next run the matrix
  This removes the potential for CS Fixer to make changes to the codebase after tests have commenced.

Matrix no longer refers to Laravel versions by "10.", but instead by full version. "." is appended when installing. This simplifies cache creation/usage, and simplifies future version-dependent steps
