chore: Allow URLs as issue

[JPeer264]

📜 Description

We had an issue in getsentry/sentry-javascript#18372 that it created an issue, even though an issue has added.

The issue was that the URL was given instead of the short link such as #100 (btw, I think this example will also be taken as false positive)

💡 Motivation and Context

Since we don't have a shared action right now, this is the only option.

💚 How did you test it?

We tested it in our repo 👍, also there is a regex101.com link as reference
