googleapis-common@8.0.2 pins google-auth-library to exact "10.5.0" (was "^10.1.0"), breaking deduplication

### Summary `googleapis-common@8.0.2` declares `"google-auth-library": "10.5.0"` — an **exact** version with no caret. The previous release, `8.0.1`, used `"^10.1.0"`. This prevents `google-auth-library` from deduplicating for any consumer that also depends on a newer `google-auth-library` directly, installing two copies. ### Where it changed The caret was dropped in the monorepo migration commit `36277d77` (PR #7606, "chore: google cloud node core migration"), which bulk-pinned sibling cross-dependencies to exact versions across `core/packages/*`. `nodejs-googleapis-common` was one of several affected — `gaxios`, `gcp-metadata`, etc. got the same treatment. Current source: [`core/packages/nodejs-googleapis-common/package.json`](https://github.com/googleapis/google-cloud-node/blob/main/core/packages/nodejs-googleapis-common/package.json) still shows `"google-auth-library": "10.5.0"`. ### Why it's a problem The pin is already **stale** — the same monorepo ships `google-auth-library@10.7.0`. A consumer that depends on `google-auth-library@^10.7.0` directly *and* on `googleapis` (which pulls `googleapis-common@^8.0.0` → `8.0.2`) ends up with both `10.5.0` and `10.7.0` installed. In TypeScript this breaks compilation, because the two `OAuth2Client` classes are structurally incompatible (each declares a `private redirectUri`): ``` error TS2322: Type 'OAuth2Client' (google-auth-library@10.5.0) is not assignable to type 'OAuth2Client' (google-auth-library@10.7.0). Types have separate declarations of a private property 'redirectUri'. ``` ### Repro A package depending on `googleapis@^173` and `google-auth-library@^10.7.0`, type-checking any use of `google.auth.OAuth2` against `google.drive(...)`. ### Note `8.0.2` has no source changes vs `8.0.1` (no commits touched the package `src/` between the two releases) — it appears to be a dependency-repinning/version-bump release, so the exact pin looks like an unintended artifact of the migration tooling rather than a deliberate constraint. ### Expected Restore a caret range for `google-auth-library` (e.g. `^10.1.0` or `^10.7.0`) in `googleapis-common`, and ideally across the other siblings repinned in #7606.
