build: Remove git-clone package from docs manifest, pull package in make.jl

The version in the docs manifest would not match the new release,
since the release is not registered yet.
This commit avoids testing the documentation build with the wrong package version.

dev: Fix contributor/maintainer release guidelines

New guildelines are in line with Julia's Registrator.jl process.

docs: Add Windows CI badge and update installation command

dev: Avoid running NetCDF tests on Windows (currently broken)

Can't use `broken=cond` with the @testset macro :(

dev: Mark NetCDF tests as broken on Windows

The NetCDF_jll/HDF5 issue will need more debugging on Windows.

dev: Attempt to mitigate NetCDF Windows issue

The NetCDF write test fails on Windows, perhaps something similar to:
https://github.com/Alexander-Barth/NCDatasets.jl/issues/164
Try to mitigate by forcing an older NetCDF_jll version for now.

dev: Check if NetCDF/NCDatasets is causing the Windows error
