Allow option to remain on v2 branch when checking for updates [enhancement]

[stevenya97]

Description

With the new v2.2.4 update, it seems currently v2.2.3 is stuck with only upgrading to v3 via the 'check for update' modal. Would be great if there was a setting/change to include/exclude major version upgrades. i.e. v2.2.4 can smoothly update to v2.2.5 without needing to visit the github repo.

Rationale

Only way to get the new v2.2.4 update it seems is to visit the github repo. Some apps have the option to select between checking for 'all versions/branches' and the 'current branch'. This makes sure that any important updates are still delivered to users regardless of which version. I imagine the percentage of users who regularly check the repo releases page compared to overall users is not as high.

Additional info

Thanks again for keeping v2 updated with the launch of v3!
