Upload smaller compressed file in github.com/docker/compose/release

[6769]

Description

The files uploaded in release page is uncompressed, which will need more network bandwith and time to download.

For example, using normal zip format could reduce to 1/3 file size of original file.

Suggest: upload compressed file instead of raw file. I guess it will only need to add one more step in github-actions.
