Bug 1990505 [wpt PR 55040] - Ignore WEB_FEATURES.yml for update-wasm-tests workflow, a=testonly

Automatic update from web-platform-tests
Ignore WEB_FEATURES.yml for update-wasm-tests workflow (#55040)

Currently, the update-wasm-tests workflow removes all the existing WASM
test files before copying over the new tests.

This means that we cannot land WEB_FEATURES.yml files for WASM because
they would be removed during the next run of the workflow.

This change moves to using rsync and excludes WEB_FEATURES.yml files.

This will allow WEB_FEATURES.yml files to persist between workflow runs.

Given these generated PRs are still manually reviewed, incoming PRs
with changes to the file names will be caught by the WEB_FEATURES linter
And reviewers can update them if needed.
