GoASTScanner/gas project has been renamed

FYI.

The project 'github.com/GoASTScanner/gas' you're using in your SAST project has been renamed to https://github.com/securego/gosec.

Thought I'd let you know as it may break your tooling :-)

[Updated description:]

• Create a new Gosec project (gitlab-org/security-products/analyzers/gosec!6 (merged))
• Update https://gitlab.com/gitlab-org/security-products/sast to use the new project instead
• Update documentation and gitlab.com
• Update Security marketing Deck https://about.gitlab.com/handbook/marketing/product-marketing/#security-deck
• Update QA to reflect this change
