Feat: bitbucket app

[x-stp]

fork off brandonjyan:bitbucketapppassword which lived here https://github.com/trufflesecurity/trufflehog/pull/1498

The previous complex logic has been replaced with a clean, single-pass approach using a unified credentialPatterns slice for simplicity and performance.

The entire detector has been brought up to current project standards, attempt w/ cleaner regex with named capture groups and improved resource handling.

xxlarge bench is 2x faster.

still not really satisfied as these regexes are quite slow.

@amanfcp, thx for the pointers, I tried to port the feedback in while going through some more recently added detectors. This should be ready for a fresh look when you have a moment; though I am not a fan of the slow regexes.

Thanks @x-stp for incorporating the pointers. Can you please resolve the conflicts?

detector code already lacks uniformity across various files, we should try to stick to the core format as much as we can.

Hi @bugbaba

I will go over the comments soon and get back to you.

Thanks!
