`parallel/test-inspector-dom-storage` writes to current working directory

[richardlau]

parallel/test-inspector-dom-storage (added by #61139) is writing localstorage.db to the current working directory. This is counter to the expectation that tests write to a temp directory (e.g. via common.tmpdir) that gets cleaned up afterwards.

e.g.

$ pwd
/tmp
$ ls -al
total 0
drwxrwxrwt. 1 root root  6 Apr  9 13:43 .
drwxr-xr-x. 1 root root 29 Apr  9 11:56 ..
$ ~/sandbox/github/node/out/Release/node ~/sandbox/github/node/test/parallel/test-inspector-dom-storage.js
NOTE: The test started as a child_process using these flags: [
  '--inspect=0',
  '--experimental-storage-inspection',
  '--localstorage-file=./localstorage.db'
] And these environment variables: {} Use NODE_SKIP_FLAG_CHECK to run the test with the original flags.
