fix(lint): ignore ruff PLR0917 so trunk passes ruff check

[claudespice]

ruff check spicepy tests — the command the Lint with ruff job runs — fails on trunk itself with two errors, so every open pull request inherits a red ruff job regardless of what it changes:

PLR0917 Too many positional arguments (6 > 5)
   --> spicepy/_client.py:239:9
PLR0917 Too many positional arguments (7 > 5)
   --> spicepy/_client.py:332:9

Verified against a clean checkout of trunk (a199cfa) with ruff 0.16.1: two errors, no branch involved.

Why ignore rather than refactor

The lint config already ignores PLR0913 ("Too many arguments in function definition"), and both flagged constructors carry an in-code # pylint: disable=R0917 — pylint's name for this same rule. The decision to allow these signatures was already made and recorded in two places; only ruff's half of the pair was missing from ignore.

Client.__init__ is the public SDK constructor. Satisfying the rule for real would mean making its parameters keyword-only, which breaks every caller that passes them positionally — not an acceptable trade for a lint warning the project has already opted out of under its pylint name.

Test plan

• ruff check spicepy tests → All checks passed! (was: Found 2 errors.)
• black --check spicepy tests → unchanged, 22 files clean
• No source files touched; the change is two lines of lint configuration.

Closing as a duplicate — #176 already carries this exact fix, and it predates this PR by five days.

I opened this after confirming ruff check fails on a clean trunk, but I did not check the open PRs from other authors first. #176 adds PLR0917 to the same ignore list with the same reasoning (positional counterpart of the already-ignored PLR0913; making the client constructor parameters keyword-only would be a breaking API change), and additionally fixes the spice add spiceai/quickstart registry failure in test.yml that this PR does not touch. #176 is strictly the better change and its checks are green.

Sorry for the noise.
