Subject: [PATCH] transmission-rpc: relax version typing_extensions

Relaxes the version constraint for typing_extensions, as the currently
released version does not allow typing_extensions 4.0.2.0.

This commit fixes that, until a new version of transmission-rpc
is released, which bumps the dependency.
