fix: Add patch to special handle targetPlatform with openvsx

Description

This MR addresses this bug https://gitlab.com/gitlab-com/request-for-help/-/issues/2405 by adding some parameters that can be used to tweak Open VSX's resourceUrlTemplate to be more reliable. See this thread for the full investigation.

From commit:

• See https://gitlab.com/gitlab-com/request-for-help/-/issues/2405#note_2366728315
• At the time, open-vsx.org doesn't support {version}+{targetPlatform}
• It also expects targetPlatform as a query param
