so basicaclly, in the
download older versions section of pico-8,
there's a file named "rc", heres a image:

if you try to access it, it says
Forbidden

You dont have permission to access
[REDACTED]
also theres some other weird things,
like pico-8 0.0.3 being at the latest section
for some reason

Presumably "release candidate". It's also the earliest so that would make some sense. Also, please remove your second image as it contains the link to the download, which does not authenticate users so they could download it for free.

oh sorry XD

thats weird, theres a 0.0.1 in that section,
so is this possibly a eariler version than that? (consider 0.0.3 is near it)

The link is still in the post.

where is it in the 2nd image?

It's text in the post.

fixed it
