Ubuntu 24.04 minimal images don't ship the alacritty terminfo entry.
SSH forwards the local TERM value, so connecting from an Alacritty
session triggers "'alacritty': unknown terminal type." on the remote.

Adds AcceptEnv TERM to sshd_config and copies /usr/share/terminfo/a/alacritty
from the Ansible controller to /etc/terminfo/a/alacritty on each target.

Relates to range42/range42#227.

+## configure/terminfo — install alacritty terminfo on remote hosts
+##
+## Ubuntu 24.04 minimal images do not ship the alacritty terminfo entry.
+## SSH forwards the local TERM value, so connecting from an Alacritty session
+## triggers "'alacritty': unknown terminal type." on the remote.
+##
+## This play copies the alacritty terminfo binary from the Ansible controller
+## (where Alacritty is installed) to /etc/terminfo/a/alacritty on each target,
+## and configures sshd to accept the TERM environment variable from the client.
+##
+## Caller: scenarios import this via `import_playbook` in their stage_01,
+## overriding `hosts` to the relevant inventory group (e.g. r42_admin_services_lab_group).
+## Relates to: range42/range42#227
