Bump numpy

[savente93]

Issue addressed

Fixes #614

Explanation

Since numpy 1.22 is EOL now, it would be good to update so that people don't use unsupported versions. Since 1.22's EOL is in 2 months (source: https://endoflife.date/numpy) I've decided to just bump it to 1.23 directly. this gives us 8 months before we need to update further so that seems like a good idea. Currently the numpy version esolves to 1.24 (in my environment) so using 1.23 should be fine for the time being.

I've also added a dependabot alerting so that we are notified of these things a bit more frequently. Sadly it doesn't support conda dependencies, but since our conda dependencies mirror that of pip (it's built from pyproject.toml) having alerts for pip EOLs is a close enough analog imo, we can always investigate further from there if necessary.
