ci: use micromamba and uv and also install ROOT (#69)

* use conda in ci and install root

* comment out root install for now

* attempt micromamba

* attempt fix

* let's try root

* probably like this

* fix?

* do not upgrade pip

* add root import and version print

* is this needed?

* sanity check

* use correct shell

* remove root version check

* add default shell

* try uv

* maybe this will work

* i don't understand this

* I'm done with uv

* Revert "I'm done with uv"

This reverts commit ecbd016.

* oh it needs editable mode
