Check for Update always shows update for same version

[eumario]

Describe the bug After updating to v0.1.3, Updater does not take into account -release tag when checking version, need to fix this.

To Reproduce Steps to reproduce the behavior:

1. Go to Settings > About
2. Click on Check for Updates
3. See there is an update, when on the current version.

Expected behavior Should only show update when version has changed.

Complete the Following:

• OS: Any
• Version v0.1.3

Additional context With the addition of the -dev and -release tags to the Version string for Godot Manager, when matching against Github's release, it isn't taking into account the addition of the -release tag. Should only do the update, when the numeric string matches.
