Tidy up @fedify/fixture docs

Drop the misleading deno.json snippet from the fixture README:
the workspace already resolves @fedify/fixture from the in-tree
source at the repository root, so contributors do not need to
add an `imports` entry, and showing one suggested otherwise.

Scope the LogTape buffering note to Deno, since the Bun and
Node.js dispatchers do not configure LogTape, and replace the
two separate `LOG=always` invocations with the single
`mise run test:deno` form that contributors actually use.

Fix the JSR reference link to point at jsr.io (the canonical
host) rather than the jsr.dev redirect.

Drop the gratuitous spaces around the slash separating
`TestSpanExporter` and `createTestTracerProvider()` in
CONTRIBUTING.md so the pair reads as a single label.
