feat: add Tailscale version and ping inputs to Helmfile deployment wo… (#307)

…rkflow

This update introduces two new optional inputs for the Helmfile
deployment workflow: `tailscaleVersion` and `tailscalePing`. The default
values are set to `1.98.9` for the Tailscale version and a specified DNS
name for the ping target. Additionally, the hardcoded version in the
deployment job has been replaced with the new input variable. Unused
code related to waiting for Tailscale readiness has been commented out
for clarity.
