Remove webui

[Qing0731]

The effects of webui and action are the same, so there is no need for both to exist simultaneously. Therefore, webui should be removed

[JingMatrix]

It is fine to co-exist for this monent.
There is no special attention needed to maintain it.

[Keeperorowner]

It is unnecessary to have two buttons with exactly the same function in the lsposed module of the root manager. One of them should be removed

[rifsxd]

A webui is just useless to call the same thing that action calls, plus all root manager has actions and magisk alone doesn't have webui so it's just unnecessary to keep webroot

You also need to remove the "generateWebRoot" Gradle action.

You forgot to remove its caller, https://github.com/JingMatrix/LSPosed/blob/f081aa38990cbb9ec3d5a2787a5ec268fd9eed9e/magisk-loader/build.gradle.kts#L175

I will merge this when you finish cleaning the gradle configurations.

Be patient, @Keeperorowner, this is not a urgent pull-request, we can still wait for some more comments (or not).

This PR looks good to me.
