Networkmanager takes 3x longer to connect to wifi on wake on 20.10 compared to 20.04

[Corbin]

Networkmanager upstream has already created a patch to fix this bug, which they backported to nm 1.26, which Groovy uses.

The upstream fix can be found here-

https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/5454681ab76ee02cfa85d65e29005b974efb3c52

This, as far as I can tell, meets the guidelines for ubuntu's SRU policy.

In addition, given that Hirsute Hippo will also be using nm 1.26, this fix will have a broader impact than just groovy.
