docs: fix callout rendering and align branding with Ping Identity

The GitHub [!IMPORTANT] callout was breaking because prettier reflowed
consecutive blockquote lines into a single line; a blank '>' separator
keeps the alert marker isolated on its own line. Also collapsed the
nested **...** pair inside an already-bolded sentence, and updated the
remaining ForgeRock text references (non-URL) to Ping Identity for
consistency with the rebrand, per review feedback.
