Instead of using an `import_map.json` file to define the versions for dependencies, they are now defined directly within the import. Since the `import_map.json` file should not be used anymore and instead a `deno.json` file per function should be used, we decided to define them directly with the code. The overhead compared to a `deno.json` file per function shouldn't be that large and it makes using functions in a self-hosted setup easier.
