fix: functions download

[7ttp]

TL;DR

fix docker based functions download so _shared files are extracted correctly

prob

when docker is used, the cli was binding only supabase/functions/<slug> and unbundling to /home/deno
for functions that import ../_shared/*
those files resolve outside the bound function folder, so _shared is missing after download
the --use-api path works because it does not use this docker bind layout

sol

changed docker extraction to bind supabase/functions as the writable root and unbundle to /home/deno/<slug>
IMO this keeps function files in the function folder while allowing _shared to be written as a sibling directory

added a smol test as well for this

ref:

• closes bug: folder extraction not working #5086
• closes _shared folder not extracted with docker #5000
