chore(deps): remove eslint-plugin-etc

The plugin is unmaintained, only supports eslint@^8 as a peer dependency
and pulls a stale @typescript-eslint/*@5 / tsquery chain, including
braces@3.0.3 (GHSA-vfj7-8cjw-p6xm).

etc/no-assign-mutated-array is replaced by unicorn/no-array-sort; the
only hit is fixed by using toSorted(). etc/no-implicit-any-catch is
covered by @typescript-eslint/no-explicit-any. etc/no-deprecated and
etc/no-commented-out-code were already off.

Same as podman-desktop/extension-kubernetes-contexts#773
