changedetection-io: add playwright container

[amedranogil]

Is your feature request related to a problem?

one of the coolest features of changedetect is not available from the get-go: browser steps and visual filter selector. this allows easy automation of browsing to get to the information which is to be monitored, which sometimes can be difficult to define otherwise.

Describe the solution you'd like

following the documentation, update the chart so that a second container is launched with playwright, and configure the appropriate env to point to it (using k8s DNS resolution, no further node port mapping should be necessary).

Describe alternatives you've considered

I installed the playwright container, and updated the env variables manually.

I added the Changedetection chart, but Playwright requires SYS_ADMIN privileges and a sidecar, so I decided to not include it on initial release, but I’ll see if in the future if we can do it without giving it God Mode
