astro env variable update
This command is only available on Astro.
Set the value of an environment variable. By default this command upserts: if the key doesn’t exist, the CLI creates it. Pass --strict to fail when the key is missing. Use --from-file to bulk-upsert variables from a dotenv file.
The platform API doesn’t allow toggling the secret flag on an existing variable. To change whether an existing variable is secret, delete it and recreate it.
