[Serverless Functions]: Update environment variables in a dedicated tab in settings > Functions, not a .env file

[martmull]

Why?
Updating a .env file is not a very common way to add and update environment variables

What?
We want to create a dedicated table in the serverless function detail view to CRUD env variables, and remove the .env file
We can add a new tab, or add a new section in the setting tab


@Bonapara what do you think?

Technically, we could also store environment variables in a dedicated encrypted JSONb column in the metadata.serverlessFunction table and use that to store environment variables instead of a file

To do also

• move serverlessFunction from metadata to workspace_schema
• add a serverlessFunctionVersion table
