Support for containers (docker, etc...)?

[zAlweNy26]

Describe the feature

I think it would be nice to also add an isDocker and/or isContainer methods, so everything you need is in one module and you don't have to install the is-docker or is-inside-container packages separately :)

Additional information

• Would you be willing to help implement this feature?

For detecting docker from the main subpath, we need to use filesystem API which reduces platform agnostic nature of std-env.

We might port it as a subpath export though like { isDocker } from "std-env/docker") (https://github.com/unjs/listhen/blob/main/src/lib/docker.ts)

It seems a good way to me
