Fix weekly pulumi/pulumi update (#501)

Fixes: #497 

This PR follows the `weekly-pulumi-update` CI workflow steps to update
our `pulumi/pulumi` dependency, with manual intervention to resolve
tooling update conflicts. Before generating the SDKs, it's necessary to
update the language tools and otel packages to ensure compatibility with
the latest changes.

Additional command executed for the manual updates:

```sh
TOOLS=(
    "github.com/pulumi/pulumi/sdk/go/pulumi-language-go/v3"
    "github.com/pulumi/pulumi/sdk/nodejs/cmd/pulumi-language-nodejs/v3"
    "github.com/pulumi/pulumi/sdk/python/cmd/pulumi-language-python/v3"
    "go.opentelemetry.io/otel/exporters/otlp/otlptrace"
)

for TOOL in "${TOOLS[@]}"; do
    go get -u $TOOL
    go mod tidy
done
```

`github.com/pulumi/pulumi/sdk/go/pulumi-language-go/v3` requires Go
v1.24
