Serialize Deno check tasks behind install in mise test

Running `mise run test` was intermittently failing in the install
step with `NotFound: Unable to get CWD` while loading the yaml CJS
package as part of `@fedify/vocab` codegen.  Reproduction with
`(deno lint &); deno task install` showed the race is triggered
whenever another Deno process starts concurrently with the
codegen process.  Failure rates measured across stable releases:

 -  Deno 2.6.10: 2/10
 -  Deno 2.7.7:  3/10
 -  Deno 2.7.13: 3–5/10
 -  Deno 2.7.14: 4/10

So neither upgrading nor downgrading Deno avoids it.

The root cause is the well-known race in Deno's
`nodeModulesDir: "auto"`.  When multiple Deno processes start at
once they each try to manage `node_modules/.deno/` and the
`node_modules/@fedify/*` workspace symlinks (verified with
`strace`: deno lint unlinks and recreates these symlinks at
startup, and the `.deno.lock.poll` file is also rewritten).  Under
that race, the CJS loader for `yaml@2.8.3` can hit a state where
`Deno.cwd()` returns NotFound from inside
`Module._nodeModulePaths`, killing the codegen subprocess.  See
the related upstream report:

denoland/deno#33311

Add `wait_for = ["install"]` to the Deno-based `check:*` tasks
(`check:fmt`, `check:lint`, `check:types`, `check-versions`,
`check:fixture-usage`).  `wait_for` is mise's optional
dependency: when `install` is already in the queue (as it is via
`prepare` from `test:deno`/`test:node`/`test:bun`), the check
tasks wait for it to complete before starting their own Deno
processes; when `install` is not queued (e.g. running `mise run
check` on its own), the tasks proceed immediately.  Empty Deno
runs left alone (`check:md`, `check:manifest:workspace-protocol`)
are unaffected.

With this change the previously flaky reproducer succeeded 10/10
times under the same parallel load.
