Replace custom trim_ascii_start with the standard library method

Browse Source 
The local trim_ascii_start function in the markdown parser duplicates
<[u8]>::trim_ascii_start() from the standard library (stable since 1.80).
Remove the custom function and call the stdlib method directly.

No behaviour change.
