Subject: [PATCH] Add precompile signatures to Markdown to reduce latency.
 (#55715)

Fixes #55706 that is seemingly a 4472x regression, not just 16x (was my
first guess, based on CondaPkg, also fixes or greatly mitigates
https://github.com/JuliaPy/CondaPkg.jl/issues/145), and large part of 3x
regression for PythonCall.
