Fix docstrings that name parameters the functions do not have

[VenishPaneliya]

Nine Sphinx field entries name an argument the function does not take. Sphinx renders each as a parameter that does not exist, while the real argument gets no entry at all.

file	function	documented	actual
ops/jit.py	trace	ignore_warnins	ignore_warnings
ops/provenance.py	get_provenance	tensor	x
ops/provenance.py	detach_provenance	tensor	x
infer/mcmc/util.py	initialize_model	ignore_jit_warnings	skip_jit_warnings
infer/reparam/reparam.py	Reparam.apply	name	msg
distributions/coalescent.py	__call__	time	t
contrib/funsor/.../enum_messenger.py	queue	q	queue
contrib/epidemiology/compartmental.py	compute_flows	state	prev, curr
contrib/epidemiology/compartmental.py	generate	:pram	:param

Several of these are self-evident from their surroundings:

• ignore_warnins is simply missing a letter.
• :pram dict fixed: is the only :pram in the package — every other field in pyro/ is a correct :param.
• get_provenance / detach_provenance sit directly below extract_provenance, which has the same (x) signature and already documents :param x: correctly. I reused its exact wording for get_provenance, since that function's own summary says it reads "a recursive datastructure possibly containing torch.Tensor s" rather than a tensor; detach_provenance keeps the torch.Tensor type, matching its x: _Tensor annotation.
• Reparam.apply documents name, but the entry itself describes "A simplified Pyro message with fields…", i.e. msg.
• CoalescentRateLikelihood.__call__ documents time while the :type t: int or slice line just below already refers to t.
• initialize_model documents ignore_jit_warnings; pyro.util.ignore_jit_warnings is a separate context manager, which is likely where the name came from.

compute_flows — the one that needed more than a rename

compute_flows(self, prev, curr, t) carried this entry:

:param dict state: A dictionary mapping compartment name to current
    tensor value. This should be updated in-place.

That text is copied verbatim from transition(self, params, state, t) earlier in the same file, where state is a real argument and is updated in place. compute_flows takes two dicts and returns a new one — neither prev nor curr is mutated, in the base implementation or in either override in models.py. So the entry is replaced with one per argument and the in-place note dropped. transition's own entry is left untouched.

Deliberately not touched

• contrib/mue/models.py and contrib/mue/missingdatahmm.py have the same class of mismatch, but nothing in the package imports contrib.mue.models, so I left that area alone rather than patching docs there speculatively.
• distribution.sample, importance.py, and ops/einsum look like hits to a naive scan, but they document genuine **kwargs keys (e.g. cache_path is read via kwargs.pop("cache_path", True)), which is correct as written.

Docstrings only, no behaviour change. ruff check and ruff format --check pass on all seven files, and every name above was confirmed against inspect.signature on the built package.
