fix: escape + in Base64 string regex pattern

[vishwaksen-1]

Description

Fixes the unescaped + character in the Base64 alphabet regex pattern.

Problem

The + character in line 20 was not escaped in the regex pattern /ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/. This caused it to be interpreted as a regex quantifier (meaning "one or more of the preceding character") instead of a literal + character that is part of the Base64 alphabet.

Solution

Escaped the + character as \+ to match it literally.

Changed:

- string: /ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

To:

- string: /ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789\+/

Testing

• Ran python scripts/lint.py on the modified file
• Verified the pattern now correctly matches the Base64 alphabet

Closes #1101

Yes I'll go through that.

It was a mistake on my end, I was accidentally running liter on previous version rather than the one I edited and hence missed it 😅.

I think it works now.
