fix(extractors): detect ssrf in needle methods

[google-labs-jules]

What

Updated the ssrf and ssrf-outbound-http regular expressions in src/websec_validator/extractors/surface.py to match methods called on the needle module, such as needle.get(url).

Why

During a check against the websec-corpus/NodeGoat application, an SSRF vulnerability located in app/routes/research.js was completely missed by the existing regex. The vulnerability was triggered by a call to needle.get(url). The existing regex correctly identified needle(url) but didn't allow optional methods like axios did.

Risk

The risk is low. This broadens the match to methods on needle exactly identically to how axios is treated (needle(?:\.\w+)?). We added a regression test for this specific vulnerability in tests/test_pentest_regressions.py and confirmed websec proof correctly parses NodeGoat and reports the ssrf-outbound-http match. All tests pass and docguard documentation changes (incrementing the test count) are in sync.
