Fix upstream Go templates bug with reversed key/value assignment

The template packages are based on go1.20.5 with the patch in befec5ddbbfbd81ec84e74e15a38044d67f8785b  added.

This also includes a security fix that now disallows Go template actions in JS literals (inside backticks).

This will throw an error saying "... appears in a JS template literal".

If you're really sure this isn't a security risk in your case, you can revert to the old behaviour:

```toml
[security]
[security.gotemplates]
allowActionJSTmpl = true
```

See https://github.com/golang/go/issues/59234

Fixes #11112
