syncing conda recipe when dependencies in setup.py change

[edublancas]

I realized that when we update dependencies in the setup.py (example), the PR that the bot opens for conda-forge does not update them - so we need to fix this.

the PR will break when new dependencies are added, removed but it'll pass when an existing dependencies is changed. e.g., from pkg>=1 and pkg>=2

looks like this is what want: https://twitter.com/condaforge/status/1647933355877445633

example:

this is the PR that the conda bot opened: conda-forge/jupysql-feedstock#10

it didn't update the dependencies: https://github.com/ploomber/jupysql/blob/ca49215ae5bcb43822c76c7ebb22cfe430550127/setup.py#L21

applied this to the jupysql recipe, will propagate to other packages if it works well: https://github.com/conda-forge/jupysql-feedstock/blob/main/conda-forge.yml

Cool let's see if it reduces the overhead.
