Replace lark-parser with lark in the environment files.

[chrisjonesBSU]

This was originally added as part of #574, but that PR might have to sit open for a while until we want to drop 3.9 and support 3.13, so I figured I'd add the lark related changes to a separate PR. This should get rid of one deprecation warning, plus makes sure we're using updated versions of lark.

lark-parser was the old conda environment name for the lark package, it's now just lark, but it's the same package.

I'll open an issue in the foyer feedstock so we remember to change it there as well.
