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

v0.3.10rc2

This release candidate fixes a binary packaging issue from https://github.com/vyperlang/vyper/releases/tag/v0.3.10rc1.
The fix was applied in #3594.

What's Changed
