Add page selection for app version

[imaperson1060]

• Add page switcher for version selection (specifically YouTube) because the recommended version would not appear on the first page of results

Addresses issues #666, #667, #674, #676, #680, #681, and probably more that I'm too lazy to find

Detailed explanation:

• Currently, the version list is pulled from the first page of recent releases for the YouTube app on ApkMirror.
• Since the patches haven't been updated for a while, the recommended version is no longer on the first page of results.
• This PR adds "Next" and "Previous" buttons for page navigation, which allows the recommended version to be selected within Revanced Builder
