Remove click pin

[rosesyrett]

The latest version of click addresses the typing issues of click.group() meaning we should be able to unpin it now.

[rosesyrett]

The best way I can see is explicitly going,

click!=8.1.0,!=8.1.1,!=8.1.2

etc until 8.1.4. It seems our issues are fixed only in 8.1.5. This seems messy to me but I'm happy to implement it.

That sounds like an overkill, it's only the type checking that has problems, right?

Should be able to do click>=8.1.5,<8.1.0. See PEP508

I thought everything up to and including 8.1.3 worked, and just 8,1,4 and 8.1.5 didn't? So:

click>=8.1.5,<8.1.4 or click>=8.1.5,<=8.1.3 if you wan't to be extra clear

[abbiemery]

Turns out it really doesn't like refining excluded ranges with inequalities, and since it's only 2 versions which don't work lets just pin those.
