Check variable value before update

[six7]

Why does this PR exist?

Closes #3169

Variables weren't checking if they are supposed to update, they just did.

What does this pull request do?

With this change we're making it so that we only update the variable value when the variable value differs from the new value.

Testing this change

Create a few variables, hit Publish in Figma, and then hit export again. In the production version you'd now get another blue dot on the library icon, in this version you don't.

Additional Notes (if any)
