[PATCH] MAINTAINERS: fix '*' wildcard formatting

[Randy Dunlap]

It seems that these wildcards confuse some parser (docutils, sphinx,
or maintainers_include.py), so quote them to avoid this issue.
Also insert a hyphen ('-') before "all files" in several places
to make the html output easier to read.

Fixes this htmldocs warning:

linux-next-20260304/MAINTAINERS:40: WARNING: Inline strong start-string without end-string. [docutils]
