fix(ci): store regex in variable to fix bash parsing error (#564)

The regex pattern for parsing conventional commits contained special
characters (parentheses, brackets) that bash was misinterpreting,
causing "syntax error in conditional expression: unexpected token ')'"

Fix by storing the pattern in a variable first, which prevents bash
from parsing the special characters during script expansion.
