Improve Tokens Studio sync provider to pull all token sets

Describe the bug
Currently when pulling data from Tokens Studio provider the backend return a limited number of tokenSets (100).

To Reproduce
Steps to reproduce the behavior:

1. Link 'Tokens Studio sync provider'
2. Pull the data
3. If you have more than 100 token sets you will see an error message and will only have 100 token sets

Expected behavior
We need to improve the request that retrieves the data to pull all token sets (from all the pages).
When working at this we should change the limit back to 25 items and make multiple requests until we get all the items.
Also, remove the error message that appears if there are more token sets
