feat: support Git LFS on plain gitea

Add an opt-in compose.lfs.yml that mounts the lfs_jwt_secret secret and
enables GITEA_LFS_START_SERVER for plain gitea (forgejo already bundles
LFS). Emit LFS_JWT_SECRET in app.ini whenever the LFS server is on so the
JWT secret is stable across redeploys instead of being regenerated on
every restart (app.ini is a read-only config mount).

Bump version 3.5.2 -> 3.6.0.

 ## Enable SSH
 
 You most certainly want to be able to access your repository over SSH.  To do so, make sure you uncomment the right lines in the configuration for `traefik`.
-
+```
-```sh
 abra app config YOURTRAEFIKAPP
 ```
-
 There uncomment or add these lines:
-
+```
-```sh
 GITEA_SSH_ENABLED=1
 COMPOSE_FILE="compose.yml:compose.gitea.yml"
 ```
-
 Then redeploy traefik:
-
+```
-```sh
 abra app undeploy YOURTRAEFIKAPP
 abra app deploy YOURTRAEFIKAPP
 ```
-
 You might need to wait a bit.  To check if it worked, you can run
-
+```
-```sh
 telnet my.gitea.example.com 2222
 ```
-
 Once you have added a public SSH key, you can check that you can connect to your gitea server with
-
+```
-```sh
 ssh -T -p 2222 git@my.gitea.example.com
 ```
