chore: Whitespace consistency & MD compatibility

Description:

- follow-up to my previous PR #6060
  (chore: MarkDown Note marker compatibility spacing)

Main directory: /browsers/

This is a follow-up attempt to standardize the MarkDown Note bubbles
by adding the recommended single space after the quote marker.
MarkDown codestyle & whitespace usage consistency is the main goal here.

Additional proposed changes:
- Remove redundant end-of-line (EOL) whitespace
- Simplify blank space usage in bullet point lists/numbered lists to 1
- Replace some tab characters with 4 blank spaces (GitHub compatibility)
- Reduce redundant blank line whitespace usage:
    - remove excessive blank lines between sections
    - remove surplus blank lines in minimal bullet point lists

File-specific improvement change:
browsers/edge/microsoft-edge-kiosk-mode-deploy.md
- Add back missing table readability spacing and cell dividers.

Ticket reference or closure:
None that I know of (at least not yet).

Additional notes:
- I have split this modification chore into sub-folder sections
to keep the number of files within a reasonably manageable amount.
- Some of the whitespace changes could not be applied due to layout.
