en: Fix description of env and add description of eval

[jjerphan]

Main changes: The description of env was the one of eval. It has been modified so that both appear correctly.

About translations: I can submit PRs for French, Spanish, Italian and German if this one is approved.

@Psycho7: I saw you are merging PRs. Can you have a look at this one, please? Thank you! :)

[jjerphan]

Hello @jlevy ; can you review this PR?
Thank you!

[jjerphan]

Hey @Psycho7, could this be merged? :)

[Psycho7]

Hi @jjerphan , I'm sorry I'm only the maintainer for ZH translation. And I don't even have the privilege to merge PRs... I'm sorry.

Hello,

No problem. It looks like @jlevy isn't active anymore 🤔

[Psycho7]

I agree with you.

And you'll find this on the top of this repo.

Note: I'm looking for a new (and potentially paid) lead author to help expand this to a more comprehensive Guide. While it's very popoular, it could be both deeper and more helpful. If you like to write and are close to being an expert on this material and willing to consider helping, please drop me a note at josh (0x40) holloway.com. –jlevy, Holloway
