Bug Fix: Automatic issue linking escaping inline codeblocks

[oskarnurm]

Description

While working on #1724, we discovered that the githubinfo passive listener incorrectly triggers on GitHub issue references inside inline code blocks, provided the code block does not start at the beginning of a line.

Steps to Reproduce

Send the message "I am looking at python-discord/bot#123 right now"

Expected Behaviour

Should not trigger the bot's passive listener.

Actual Behaviour

Incorrectly triggers the bot to fetch the issue.

Known Impacted Platforms

• Web
• Desktop
• Android App
• iOS App

Possible Solutions

I think the issue stems from:

sir-lancebot/bot/exts/utilities/githubinfo.py

Lines 36 to 40 in 3d83810

	CODE_BLOCK_RE = re.compile(
	r"^`([^`\n]+)`" # Inline codeblock
	r"|```(.+?)```", # Multiline codeblock
	re.DOTALL | re.MULTILINE
	)

Where the CODE_BLOCK_RE regex anchors the match exclusively to the start of the string/line.
A possible fix would be to remove ^ from line 37:

CODE_BLOCK_RE = re.compile(
    r"`([^`\n]+)`"    # Removed the ^ 
    r"|```(.+?)```",  
    re.DOTALL | re.MULTILINE
)

Would you like to implement a fix?

• I'd like to implement the bug fix
• Anyone can implement the bug fix

We can fix this when we implement #1724
