Explicitly specify rootDir to satisfy upcoming TypeScript v6. (#4599)

See [1] and [2] where the "rootDir" needs to be explicitly specified, otherwise it will default to "." unlike v5 which was defaulted to the common root folder of all input files.

This fixes a build error in the downstream Chromium repository, see https://issues.chromium.org/issues/485931998.

These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor dom/webgpu/tests/cts/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.

Comment 4

[Update Bot]

This bug is being closed because a newer revision of the library is available.
This bug will be marked as a duplicate of it (because although this bug is older, it is superseded by the newer one).

Comment 5

[Update Bot]

Updatebot encountered an error while trying to abandon the phabricator patch 284634.
Updatebot will be unable to do anything more for this library version.
