Make secret name input box resizable

We use doppler for managing Magento 2 secrets and configuration values, and those key names become long very quickly. An example key would be M2_CONFIG__WEBSITES_WEBSITENAME__CATALOG__PRODUCTS__EXAMPLE_CONFIG_KEY.

The current doppler UI doesn’t support resizing the input boxes as far as I’m aware, and when you have a lot of keys starting with the same sequences it can become really bothersome to find the correct secret.

My proposal would be to make the key name input field resizable in width so that the full name of the key would be visible instantly.
