GitHub Sync and Polish release

It's here! Version 67 of Figma Tokens with a bunch of improvements and new features. Let's get to it:

• New sync option: GitHub sync! This is the one a lot of you have been looking forward to: Store tokens on GitHub! This allows you to keep them version-controlled, use features such as branching, and create your own token pipeline by utilising GitHub Actions. Read more on the Docs.
• New sync option: URL sync! Add an external URL to sync as a Read Only user. You can also add a JSONBin and access it as a read only user provided you have the credentials - fixes #251
• Remove Resize Window from Options. You can now drag the bottom right corner of the plugin window to do that.
• You can now exclude tokens from being created as styles by having their names begin with a _, e.g. colors.blue._hue or whole groups by using _global.blue.100 - fixes #264
• Token names that contain a / in it's name are now automatically transformed to names containing . instead. Fixes #274
• Fixed a bug with colors when displayed in list mode - fixes #275
• Fixed a bug with color thumbnails not being displayed correctly - fixes #266
• Fixed how math was encapsulated and calculated inside rgba() functions - fixes #166, fixes #209
• Fixes opacity values sometimes evaluating to 0.52 in Figma
• Adds unique check to token names
• You can now enter JSON5 into the json tab and we'll convert it to JSON for you. This means you don't need to add quotes around keys and can have dangling commas at the end. Fixes #283
• Entering named colors like red, blue or green is now supported both in plugin UI And when using it to create styles, which will convert it to hex for you. Fixes #276
• Duplicate a single token to copy it's values to a new token named the same with -copy added to it's name. Fixes #142
• We now show you when a reference has a broken alias in token overview
• We now show you a preview on a token value when it contains an alias when editing or creating a token
• Fixed a bug that applied raw token values instead of applying the style when the style should've been used in a local document
• Added deep equality check to importing typography styles. These should no longer show up as changed when using Import, even though nothing changed. Thanks @tpict
