[ENH]: enforce maximum get_collections limit as 100 (#4929)

## Description of changes

Enforces maximum get collections limit as 100 as a temporary patch.

## Test plan

- [x] Tests pass locally with `pytest` for python, `yarn test` for js,
`cargo test` for rust

## Documentation Changes

We should update docs somewhere saying this is enforced.
