Copy zinit.1 to man1 directory for `man` to be able to open it

[psprint]

Description

Add a single conditional that checks if $ZPFX/man/man1/zinit.1 exists and copies it if not.

Motivation and Context

There is a manual page of zinit – in doc/zinit.1. However I suppose that it's very rarely ever open, because its location under BIN_DIR. So I thought that it should be copied to man1 dir under ZINIT[MAN_DIR] so that simple man zinit works fine.

Can you fix the zshelldoc check? $ make doc should do it.

This looks good to me otherwise.

[psprint]

@alichtman make doc didn't help, the generated docs still differ from container's docs.

[psprint]

I think that it is sufficient to copy man page to $ZPFX/man, because man searches in locations derived from PATH. If I remove $ZPFX/bin from $PATH then zinit.1 isn't found. Also man man says that $MANPATH shouldn't be used. Could someone update the docs correctly and merge the PR?

@vladdoster: I've reset to skip the faulty zsdoc commit. There are no conflicts now.
