man: clarify that --fido2-with-user-presence= may not be supported (#43266)

Reword the note for --fido2-with-user-presence= to make it clear that the
setting has no effect if the token does not support the up feature, or does
not allow the user presence requirement to be enabled or disabled for the
requested operation. Drop the surrounding parentheses and the spurious
"in other contexts" qualifier.

Apply the same rewording to the sibling --fido2-with-client-pin= and
--fido2-with-user-verification= options so the three parallel FIDO2
entries stay consistent.

Fixes #23632.
