version extraction via RegEx seems to not work with sub-folders (on SourceForge)

[DJCrashdummy]

Prerequisites
i'm not 100% sure, maybe this is very loosely related to #946.
yes, i'v read https://github.com/ImranR98/Obtainium/wiki but found nothing related to either sub-folders or SourceForge (nor an explanation of what the version extraction via RegEx takes into consideration: just the APKs name, a relative link depending on the "source" aka. distributor or the whole URL?).

Describe the bug
either i don't get completely how the version extraction via RegEx works, or it simply does not work with sub-folders (on SourceForge).

To Reproduce

1. i tried to add https://sourceforge.net/projects/domination/ to Obtainium. (no matter what URL to which sub-folder you paste, that's the URL Obtainium uses.)
2. if i just go ahead (like it usually works) Obtainium presents a list with all APKs to choose from, which is a pleasant surprise given the fact that the sorting of the APKs in sub-folders is a mess.
3. after you choose the latest one (version code 93 at the time of writing) - the version code is at least used in the file name - Obtainium correctly displays it afterwards as installed.
4. but after that the issue begins: Obtainium always displays a new version Domination (which i guess is because the newer of the 2 main folders in the repo is named like that).
5. than i thought ok, it's time to test the RegEx-function:
   as the allegedly new version is called Domination i thought this would be a good staring point... so my RegEx looks like Domination\/[\d.]+\/Domination[-_]([\d]+)\.apk. in desperation i also tried something like https:\/\/sourceforge\.net\/projects\/domination\/files\/[Dd]omination\/[\d\p{Punct}]+\/[Dd]omination[\p{Punct}]([\d]+)\.apk.+ and countless variations, but it always tells me "Release version can't be determined" (that's my translation).

Please complete the following information:

• Device: Asus Z00ED
• OS: Resurrection Remix OS
• Obtainium Version: 1.0.1

Additional context
either please tell me what i'm doing wrong at the RegEx version extraction; or making it work even with sub-folders (at least at SourceForge) would be awesome.

BTW when mentioning the wiki:
at the second bullet of the section App Sources i'm pretty sure the URL at the link version detection is wrong.
-> unfortunately i didn't find a possibility to edit the wiki, else i would have created a pull request.

This issue isn't about version extraction - I just wasn't aware of the fact that SourceForge can have nested subfolders. The current design assumes the root folder will always contain a bunch of subfolders, where each subfolder name is an app version, and the folder's contents are the APKs for that version. That's the system used by OpenCamera, the example app I used when coding this source.

The next release will have support for subfolders - then you should then be able to add this app in one of 2 ways:

• Add https://sourceforge.net/projects/domination/files/Domination/ directly
• Add https://sourceforge.net/projects/domination/, then the version string will include the subfolder, so it would be something like Domination/1.2.8 and you can use "Version Extraction" to trim it down.

Also thanks for the correction, I've updated the Wiki.
