Renames the matrix_mautrix_SERVICENAME_* placeholders in the common
mautrix bridges guide to matrix_bridge_mautrix_SERVICENAME_*, and fixes
prose in the matrix-bridge-steam role that referred to the old variable
prefix and to a misspelled (underscore-styled) systemd service name.

Part of adopting a uniform naming policy for bridge variables,
where the variable prefix matches the role directory name.

The bridge could only be installed by self-building its source code,
and its upstream repository (on src.miscworks.net) has become
unreachable (the Internet Archive last saw it alive in May 2026),
making installation impossible. The bridge was also based on the
long-unmaintained node-kakao library and carried a warning that using
it may get KakaoTalk accounts banned.

The playbook catches leftover matrix_appservice_kakaotalk_* variables
and points users to the manual uninstallation instructions.

Add a "Expose the bridge's API" section to the common mautrix bridges
documentation page (covering the /bridges/<bridge> path, the
/.well-known/matrix/mautrix auto-discovery file, how to disable it, and
the custom-bridges hook), plus a CHANGELOG entry announcing the feature.

We previously made "this playbook" a link to some specific component.
This is somewhat misleading. Reading the text and seeing that "this playbook"
is a link, one might think that "this playbook" actually links to the
playbook's home page or something, not to the specific component which
could be "installed using this playbook".

This patch adjusts the markup so that the whole phrase "installed using this playbook"
is turned into a link (to the specific component's page). This makes it
more obvious where we're linking.

This work was initially done for the Email2Matrix docs page in
1b05343aba. This patch brings the same
change to all other instances.
