Score for "Has docs for most symbols" is wrong when an export has overloads

[lowlighter]

If a symbol has overloads, then only the first one count as being documented so it lower the score

I've confirmed this is the case by publishing two releases of a package, one without overloads and one with them, and it changes the score.

This package has only one export, and with 4 overloads it reports "Currently 25% of symbols are documented.".
100/4 = 25 (this is actually how I discovered the issue)
