Remove orphan top-level integrations gitlink

[theletterf]

Summary

#243732 ([Lens] Improve transform validation checking) accidentally recorded a top-level integrations submodule pointer (mode 160000, sha 5a5d30c6ebf4fef2c4226a67c31d772ceb93230d) without an entry in .gitmodules (which doesn't exist in this repo). The intent was to add files under src/platform/packages/shared/kbn-lens-embeddable-utils/config_builder/tests/integrations/ — that part of the change is preserved; only the stray top-level gitlink is removed.

The orphan gitlink causes actions/checkout's post-job cleanup (git submodule foreach --recursive) to abort with exit 128:

fatal: No url found for submodule path 'integrations' in .gitmodules

This marks the docs CI jobs (build / build, build / vale) red on every PR that touches docs/**, even when docs-builder itself reports 0 Errors / 0 Warnings / 0 Hints. First seen on #267647.

cc @nickofthyme — most likely a git submodule add / .gitmodules interaction during local work on #243732. Please confirm nothing in the Lens integration tests actually needs a populated submodule at the repo root (the per-package tests/integrations/ directory is untouched here).

A complementary defensive fix is up at elastic/docs-actions#139 so future orphan gitlinks degrade to a CI warning instead of a hard failure.

Checklist

• No user-facing changes — release_note:skip.
• No backport needed — affects main only (the bad commit hasn't been backported).

Identify risks

• None. The change is git rm --cached integrations only. No working-tree files are removed. The Lens integration test files added in [Lens] Improve transform validation checking #243732 (under src/platform/packages/shared/kbn-lens-embeddable-utils/config_builder/tests/integrations/) are untouched.

Test plan

• Verify the file tree under src/platform/packages/shared/kbn-lens-embeddable-utils/config_builder/tests/integrations/ is unchanged.
• Verify no mode 160000 entries remain at the repo root: git ls-files --stage | awk '$1 == "160000"' returns empty.
• After merge, verify build / build and build / vale go green on a docs PR (e.g. [Docs]: Add Fleet setting for setting the task interval for version-specific policy assignment #267647) without any other change.

Thanks @theletterf I forgot to check this. We just pull down the repo to capture the panel data locally, but this is not something that is needed in kibana. Sorry for the trouble.
