[Bug]: Garden Windows binaries cannot be run because lack of code signing

[10ko]

Bug

Current behavior

Some Windows users are experiencing issues when updating and trying to run the latest version of Garden.
Some tools (e.g. Crowdstrike) are blocking users from running multiple versions of Garden because the lack of code-signing of the Windows binaries.

Expected behavior

Garden users on Windows should be able to update and run any version of Garden

Reproducible example

Workaround

Updgrade or downgrade to a different Garden version.
Different tools might allow or forbid different versions, we don't have an exhaustive list at the moment.

Suggested solution(s)

Implement code signing in the release pipeline.
