chore(ci): fix binary names in release asset upload (vyperlang#3597)

rename binary during asset upload to properly escape the filename for
the github API call.

(Github API states:
> GitHub renames asset filenames that have special characters,
non-alphanumeric characters, and leading or trailing periods. The "List
release assets" endpoint lists the renamed filenames. For more
information and help, contact GitHub Support.
