Block manual changes to releases/*.json

[captn3m0]

I'd like to disable manual commits (non-automated ones) to the releases directory. You can test the code locally and generate changes, but changes to the release files should only be made by the automation that runs.

Pros:

1. It prevents double commits (you commit one file, and the automation generates it over again, such as on this PR)
2. Automation is always tested this way.

unsure how to enforce this, think GitHub restrictions might work here (will automatically avoid pushes). Could probably setup pre-commit hooks to ignore JSON files as well.
