Compilation instructions out of date

[hlein]

Description

The documentation at https://aquasecurity.github.io/trivy/v0.41/getting-started/installation/#install-from-github-release-official still discusses the old way of building from source:

git clone --depth 1 --branch v0.41.0 https://github.com/aquasecurity/trivy
cd trivy
go install

This now fails with no Go files in /path/to/trivy

AFAIK this has not worked since 0.39.0 when Makefile was removed in favor of using mage.

No response

Suggestions

The new method appears to be to install mage as a prereq to building, and then do mage build from the toplevel dir.

go install cmd/trivy/main.go

should work.

go install ./cmd/trivy is better. I created an issue. Thanks.
