OPA v1.19.1

[srenatus]

This release uses the latest version of Go (1.26.6) to build OPA, fixing stdlib vulnerabilities in code that OPA's HTTP handler and crypto builtins use:

• https://pkg.go.dev/vuln/GO-2026-6218
• https://pkg.go.dev/vuln/GO-2026-6091
• https://pkg.go.dev/vuln/GO-2026-6090
• https://pkg.go.dev/vuln/GO-2026-6089
• https://pkg.go.dev/vuln/GO-2026-6088
• https://pkg.go.dev/vuln/GO-2026-5972
• https://pkg.go.dev/vuln/GO-2026-5026

It is otherwise the same code as v1.19.0.

Note that users building their own OPA binaries and images already control the Golang version, so this is not relevant for them.
