feat(github): add a form for the Studies using pathotypr category

[Paururo]

The category was renamed from Show and tell and had no form, so it collects whatever people feel like writing.

What it asks

Field	Required	Why
The work	yes	DOI, preprint, repository, or just a title
Version	yes	see below
Which commands	no	which of the five did the work
Marker panel	no	published Zenodo panel, or one they curated
Reference genome	yes	the most consequential detail on the form
Organism	yes	where it is being pushed past what has been validated
What you used it for	yes	one sentence
What was awkward	no	the most useful field

Two choices worth explaining

The version field carries a real warning, not a tidiness request. Before 1.0.1, classify scanned only the forward strand and missed markers on reverse-oriented contigs, and genomes with no hits were dropped from the summary rather than reported as unclassified. An analysis run on draft assemblies with 1.0.0 has to be read with that in mind, and the only way anyone ever finds that out is if the version was written down.

The reference genome is required and the panel is not. A panel read against a different assembly produces confident, wrong calls and says nothing about it. Knowing which panel was used is interesting; knowing which assembly it was read against is what makes the numbers interpretable.

Verified

The filename was checked against the live category slugs from the API, not assumed:

marker-proposals          -> Marker proposals
q-a                       -> Q&A
studies-using-pathotypr   -> Studies using pathotypr

That check exists because getting it wrong is exactly how the original marker proposal form sat invisible: it was named marker_proposal.yml against categories that never included one.
