fix(geneve): Restore session multiplication

fix(geneve): Restore session multiplication

Previous edit was restoring the correct formatting for bold text
in suite documentation by a mass replace of single asterisk
to double asterisk.
But in geneve suites, one usage of single asterisk
was numeric multiplication, which was errorneously replaces
with double asterisk (power operation).
This restores the multiplication.
