direnv: Apply nushell env transformations

In nushell, the ENV_CONVERSIONS environment variable is used to
transform the defined variables from a string to a nushell value (PATH
to a list being one of the most common uses). This commit applies
user-defined conversions to direnv-loaded variables.

This fixes binary autocompletion not being triggered for newly added
paths and makes direnv work consistently with nushell
