[PATCH v3] Documentation: Unify format for vuln sysfs

[Takahiro Itazuri]

The format for vuln sysfs files was diverge across pages. Unifies the
format as follows:

* Use list table for possible values for the sysfs files, because simple
  table does not allow line breaks for the first column; otherwise
  recognized as two different rows

* Insert 2-spaces indentation before the sysfs paths

* Wrap each possible value with single quotes

* End description with a full stop

Changes in v3
- Return to list table in favor of presevation of the existing HTML appearance
  and readability/editability in plain text format.
- Link to v2: https://lore.kernel.org/all/20240906104936.15558-1-itazur@xxxxxxxxxx/

Changes in v2:
- Use grid table over list table (applying to not only GDS but also
  other vulnerabilities)
- Link to v1: https://lore.kernel.org/all/20240903132533.26458-1-itazur@xxxxxxxxxx/
