Misspelling in man page about git-archive-file(1)

[xeniagda]

When running git extras --help, on the line about git-archive-file, it says ...to a archive.. This should be to an archive.

It appears that there are a lot of that particular spelling.

@loovjo @nicolaiskogheim
Would you send a pr to substitute the spelling, and regenerate html files and man pages? Thanks!
