Fix Click to version 8.1.8

DSH currently has Typer fixed to version 0.15.2. Typer has Click as a
dependency, but Typer 0.15.2 doesn't fix the Click version. Installing
Typer 0.15.2 therefore, by default, results in Click 8.2.0 being
installed (the latest version of Click as of now).

Unfortunately Typer 0.15.2 isn't compatible with Click 8.2.0. This
change therefore fixes Click to 8.1.8 in order to retain compatibility.
Without this fix, calling "dsh --help" on a clean install results in an
error.

Fixes #2439
