Number of Environments is limited to 30

**Describe the bug**
When you check the Environments list in the SETTINGS tab, you can only see at most 30 environments. This affects the validation of the file as it will highlight a valid environment when it is not in the first 30 environments.

**To Reproduce**
1. With a repository that has over 30 environments
2. Go to SETTINGS --> Environments

**Expected behavior**
It should show all the environments.

**Screenshots**

**Extension Version**
`v0.26.2`

**Additional context**
This should be fixed by the `paginate` method as used in this #110.

Start in the VS Code extension's SETTINGS tab and trace how the Environments list is loaded, using the paginate method referenced in issue #110 as the starting point. Reproduce with a repository containing more than 30 environments, then verify that all environments appear and valid environments beyond the first 30 are no longer flagged.
