[tarantool-patches] [PATCH] lua: remove digest.sha() and digest.sha_hex()

[Alexander Turenko <alexander.turenko@tarantool.org>]

SHA-0 is considered weak for years and was removed in OpenSSL since
1.1.0.

These Lua functions did not work since 15ed10e4, but give 'Digest
method "sha" is not supported' error for any input. Removed them to
don't confuse a user with a Tab completion.

Follow up #1722.
Fixes #4028.
