Not all env files added to Important Files

### Description

Many thanks to @haidubogdan for the great _env file_ support #9075! 👍

One little thing is missing though. The MIME resolver has support for often used variations like ``.env.local``, ``.env.dist``, ``.env.dev``, ``.env.test`` and so on, which works great.

The **Important Files** node however does only seem to add files with exactly an ``.env'' as extension.

### Use case/motivation

I would be really nice if all _env files_ would be added to the **Important Files** node.
