build: mark lsp integration test as flaky (#64085)

The lsp integration test is flaky and can fail intermittently. This change marks the test as `flaky = True` to prevent it from failing the build.

Additionally, the `no-remote` tag is updated to `no-remote-exec`. The former disables remote caching, while the test can still benefit from it.
