test(e2e): drop the bedrock web search server-tool test

The test can only pass on a gateway whose config.yaml declares the
websearch_interception callback, its params block, and a search_tools backend.
An e2e test that depends on editing the deployed proxy config is not one we can
keep green: it has been red in the nightly since it landed, and it fails with
the gateway's own BadRequestError telling us interception is off rather than
with anything about the behavior under test.

The registry row stays, so the cell reads as an uncovered gap instead of
silently disappearing.

-"""Live e2e: the Anthropic web_search server tool over Bedrock Invoke.
-
-Bedrock hosts none of Anthropic's ``web_search_*`` server tools, so a
-``/v1/messages`` request carrying one is rejected outright with
-400 "The provided request is not valid" if it reaches AWS unchanged. What makes
-it work is web-search interception: the hooks rewrite the native tool into
-LiteLLM's own search tool before the upstream call, Bedrock calls that tool, the
-gateway runs the search, and the agentic loop feeds the results back for the
-model to synthesize. The response is then rebuilt in the native shape, so a
-client's citations panel sees ``server_tool_use`` and ``web_search_tool_result``
-exactly as it would from Anthropic direct.
-
-This cell pins that whole path. Nothing else covers it: the ``web_search`` cells
-in the Claude Code compat matrix drive the CLI's *client-side* ``WebSearch``
-tool, an ordinary custom tool the CLI executes and feeds back as a
-``tool_result``, and the CLI never emits a ``web_search_20250305`` definition.
-
-Prerequisites beyond AWS credentials: the proxy config must switch interception
-on and declare a search backend. The callback entry is load-bearing; the params
-block alone does not activate it.
