tests/config: Fix config test configuration First, "XDG_CONFIG_HOME" shouldn't be named "home", as it may be confusing compared with `$HOME`, which an upcoming test will be using. Then, using a fixed location for the test is problematic. Use `$TEST_ROOT` instead.

Mark `fetchTree` as unstable again As discussed in our last meeting, we need a bit more time, but we are "time boxing" the work left to do to ensure there is not unbounded delay. Rather than putting it back underneath `flakes`, though, put it underneath its own `fetch-tree` experimental feature (which `flakes` includes/implies). This signals our commitment to the plan to stabilize it first without waiting to go through the rest of Flakes, and also will give users a "release candidate" when we get closer to stabilization. This reverts commit 4112dd1fc93c9ff03a5a4e8be773c45ebefbbd1f.
