Fixed SyntaxWarnings for invalid escape sequences in regex patterns. Two regex patterns with escaped square brackets were using regular strings instead of raw strings, causing DeprecationWarning in Python 3.12+.

Before:

re.search("\[IMG:[0-9]+\]", i)
re.search("(?<=\[IMG:)[0-9]+(?=\])", i)

After:

re.search(r"\[IMG:[0-9]+\]", i)
re.search(r"(?<=\[IMG:)[0-9]+(?=\])", i)

Added r prefix to make them raw strings, eliminating the deprecation warnings. — Sent via @AmSach bot
