fix: escape special chars in regex for toHaveTextContent fixer

[skovy]

What:

• Escape (RegExp) special characters in strings that are treated as regular expressions in the fixer for toHaveTextContent.
• Convert non-strings (eg: 100) to a string before converting to a RegExp.

Why:

So the fixer works out-of-the-box without any additional manual fixes.

How:

• Using the snippet from MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions#Escaping
