guix: fix package defenition

[ch4og]

Changes:

1. After last change to quickshell.scm with addition of polkit, module for polkit wasn't added.

2. I found that many inputs were in wrong places, some of them even repeated. Also bash-minimal should be added since we wrap binary. This caused errors like so when using as a channel:

guix home: error: profile contains conflicting entries for libxkbcommon
guix home: error:   first entry: [email protected] /gnu/store/81knrk9sar7g1syz35dgfxlnyq1gi5l1-libxkbcommon-1.11.0

3. Currenty Guix is absolutely fine with using this repo as a channel with in-tree source, so I made PR to docs

Result:

Setup:

$ grep -r quickshell /tmp/channels*
/tmp/channels.scm:       (name 'quickshell)
/tmp/channels.scm:       (url "https://github.com/quickshell-mirror/quickshell")
/tmp/channels2.scm:      (name 'quickshell)
/tmp/channels2.scm:      (url "https://github.com/ch4og/quickshell")

$ cat /tmp/quickshell.scm
(use-modules (quickshell)
             (gnu packages))

(packages->manifest
 (list quickshell-git))
