Gravity Perks 2.3.10

- Fixed issue where GC Google Sheets was getting detected as a perk due to its backwards compatibility class which could then cause errors in Gravity Perks.

- Fixed issue where notices in perk global settings were misaligned.

- Fixed issue where the plugin updater API response for perks included extra properties, such as the changelog, which could prevent plugin updates from showing up in some situations.

Fixed issue where "Enable auto-updates" would only show on perks if there was an available update.

Updated strings in the Perks tab to be internationalized.

- Fixed an issue where Gravity Perks' licensing would replace variables in the updater URLs for GS Product Configurator and prevent updates from downloading successfully.
- Added German translations. Credit: Florian Rinnhofer of sportunion.at

- Improved performance by decreasing the number of calls to `get_plugins()`.
