It's really just one of those clever little puns that Unix is known for.
e.g. "more" is a paging utility ... "less" is an alternative one, even though it doesn't show you less of the file.
"elm" is a mail reader, "pine" is a different mail reader, and they are both trees.
"man" is short for manual. Man is also the word for a male human being. "Bro" is another, affectionate word to describe a male human being.
Just another pun, not a dark scheme to alienate women from the programming world. And certainly not misogynistic language or jokes that are likely to create a hostile environment for women.
There are some possible package names that would be sexist and anti-women. This isn't one of them.
