shapely>=2 & other minimum version deps

This PR:

• resolves stipulate minimum shapely version #375
• resolves update micromamba setup in CI #376
• resolves Failing CI: geopandas + spaghetti #373

Looks like even python==3.8 is causing problems. Perhaps time to dump that and support only python>=3.9.

resolved by keeping geopandas==0.10 as minimum

In this specific case that makes sense. More broadly we might think of adopting a policy of supporting say the last three stable versions of Python?

If we did that, we'd have a decision rule as to when to drop previous versions on a case by case basis.

No idea why I am not able to get this 3.9 minimum CI environment to solve...

geopandas==0.12 was the problem

[martinfleis]

We should follow https://scientific-python.org/specs/spec-0000/ in regards to versions. Including Python. We can deviate when it makes sense (shapely 2).

I finally realized the problem was specifically with the geopandas==0.12 pin, which was not necessary. Keeping the pin at geopandas==0.10 allows for Python 3.8 environment resolution.
