Enable deployments

[ibarrajo]

Checked environment variables at the build step on the deployment GH action.

Run: https://github.com/cadence-workflow/Cadence-Docs/actions/runs/12602826174/job/35126630404

It's correct, CADENCE_DOCS_URL is redacted automatically since it's stored as a secret.

CADENCE_DOCS_URL is https://***
PROJECT_NAME is Cadence-Docs
BASE_URL is /
ORGANIZATION_NAME is cadence-workflow

In case something goes wrong, it can be deployed from a local environment:

## Production Configuration (.envrc.local)
export CADENCE_DOCS_URL=https://cadenceworkflow.io
export BASE_URL=/
export ORGANIZATION_NAME=cadence-workflow
export PROJECT_NAME=Cadence-Docs

touch static/CNAME
echo "cadenceworkflow.io" > static/CNAME
npm run deploy
