Changing `bash` lexer to `console` because it is appropriate most of
the time. Then after a manual review, some lexer have been changed.
I used `text` each time I was unsure, and for prompt outputs.
The page `/developer/building/qubes-iso-building.rst` still need to be
reviewed (look for lines starting with `$ #`).
I'm not sure about the Windows pages, should we use
[doscon](https://pygments.org/docs/lexers/#pygments.lexers.shell.MSDOSSessionLexer)
or `powershell`?
Is there an appropriate lexer for `guid.conf` content?
**Statistics - Before**
870 bash
9 python
9 c
2 yaml
**Statistics - After**
684 console
111 text
44 bash
16 yaml
9 systemd
9 c
8 python
4 ini
4 doscon
2 markdown
2 desktop
1 xorg.conf
1 xml+jinja
1 xml
1 kconfig
1 html
This suggests that the default lexer should be `console`.
