Add Easypanel as a one-click deployment option to the docs

Hi — this is Ahson Shaikh, DevOps Engineer at Easypanel. Easypanel is a self-hosted Docker deployment platform, and JumpServer has a one-click deployment template there: https://easypanel.io/templates/jumpserver

I noticed docs.jumpserver.org already has a detailed 1Panel installation guide (a similar self-hosted panel category), so I wanted to check with your team on the best way to add Easypanel too - whether that's a new page alongside the 1Panel guide or a shorter mention elsewhere. I didn't want to submit a full docs page in Chinese without a native speaker reviewing it first, and the jumpserver/docs repo has issues disabled, so opening this here instead.

Unlike the 1Panel flow (which needs separate manual MySQL/Redis setup), Easypanel's JumpServer template is a single one-click deploy - the database and Redis are bundled automatically.

Test plan

Deployed via the Easypanel template's own defaults (bundled MySQL + Redis) and confirmed it boots cleanly and reaches the login page, screenshot above.
