fix(ci): remove broken glob (#63277)

A glob that doesn't match any files got introduced in
4077b3ec22 (diff-f7c1ab1acb5e753bccdd4b092b0098fa58855899e8764b68829ada2ba9cea760R147)
which appears to confuse Gazelle, leading to `sg bazel configure` not
updating ts files.

Fixes https://github.com/sourcegraph/devx-support/issues/1029


## Test plan

Locally tested: 

1. Dropped the offending glob 
2. rm'ed `client/web/src/cody/subscription/subscriptionSummary.ts` 
3. `sg bazel configure` 
4. Observed the build file being updated accordingly.
