[edk2-devel] [PATCH v1 1/1] BaseTools: Resolve regex syntax warnings

["Joey Vagedes via groups.io" <joeyvagedes=microsoft.com@groups.io>]

Switches regex patterns to raw text to resolve python 3.12 syntax
warnings in regards to invalid escape sequences, as is suggested by the
re (regex) module in python.
