fix: canonicalize paths in the index

[bdraco]

Example case

alexpy became AlexPy and we can't see the new wheel so we need to canonicalize the path before figuring out which files to put on the html page

changed in 1.27.0

[bdraco]

https://pypi.org/simple/ seems to use the canon name for the dir, but the first package name it sees as the title of the link which is strange as you would think it would use the canon name for both.

Everything seems to work using the canon name for both which makes more sense to me

[bdraco]

https://pypi.org/simple/AIOsomecomfort/

redirects to the canon name https://pypi.org/simple/aiosomecomfort/

This seems like it will be fine and is a good fix.

It's so hard to tell though.

We can always revert if needed or change the name to be the newest package meta name
