Update sshd app's image to the version-9.7_p1-r4

[jorups]

The current version of sshd.yml contains very old base image for openssh-server (lscr.io/linuxserver/openssh-server:version-8.6_p1-r3). However, SSH tunnel mod (linuxserver/mods:openssh-server-ssh-tunnel) is already ported to the s6 v3 (https://github.com/linuxserver/docker-mods/tree/master?tab=readme-ov-file#new-v3-mods) and the base image doesn't work properly with the updated mod. More specifically mod does not modify the sshd_config file to make SSH tunnel work, hence manual modification of configuration was required. This should fix the issue https://github.com/caprover/one-click-apps/issues/1041

☑️ Self Check before Merge

• [x] I have tested the template using the method described in README.md thoroughly
• [x] I have ensured that I put as much default values as possible (except passwords) to ensure minimum effort required for end users to get started.
• [x] I have ensured that I am not using the "latest" tag as this tag is dynamically changing and might break the one-click app. Use a fixed version.
• [x] I have made sure that instructions.start and instructions.end are clear and self-explanatory.
• [x] Icon is added as a png file to the logos directory.
• [x] I've executed the checks if necessary by running npm ci && npm run validate_apps && npm run formatter (If failling run the prettier: npm run formatter-write)
• [x] I will take responsibility addressing any issues that arises as a result of this PR (maintaining this app).
