chore: reverted changes to use markdown instead of html tag for Session Timeout to ensure anchor tag works. (#2967)

## Description 
In earlier PR, had added Enterprise Badge for Session Timeout. But with
that, lost anchor tag to session-timeout.
Reverted changes to use markdown instead of html tag, so that anchor tag
is available for session timeout.
