fix: add missing nop param for full-sync

[PendaGTP]

Related to #378 (#378 (comment))

Now the full-sync script will use the new env var FULL_SYNC_NOOP and so run is noop mode if true.
This helps run safe-settings GHA since you can add this var conditionaly based on event.

Example (based from https://github.com/UCL-MIRSG/.github/blob/4695e545829b91dcddc6e36358454bc4a879f751/.github/workflows/safe-settings.yaml thanks @paddyroddy) :

Nice! maybe you can update the readme too?

Yes, I agree that updating the documentation would be beneficial.

I think it would be more appropriate to create a separate PR for GHA documentation updates, as I'm planning to make other documentation improvements unrelated to this PR.

But if updating GHA documentation in this current PR is required to merge it, I can update it.

We have different implementations for boolean environment variables.
For example, CREATE_PR_COMMENT is handled as a string, while with this changes FULL_SYNC_NOP is implemented as a boolean value. This is reflected in the different approaches in our unit tests.

I think it would be beneficial to standardize how we handle boolean environment variables across the project. Once we decide on the preferred implementation (string or boolean), I can create a new PR to refactor the existing code for consistency.
I can also update my changes to fit current implementation.
