Fix documentation in Universum.Lifted.File to mention correct module

[serhiip]

Description

There is a typo in referenced module names - there is no file related functions in Data.Text (correct module is Data.Text.IO). This PR fixes the issue.

Issue could be observed here http://hackage.haskell.org/package/universum-1.5.0/docs/Universum-Lifted-File.html

LGTM, thanks. We should merge #216 first to make CI pass here, then you'll have to rebase on latest master.

[serhiip]

As #216 is merged I've rebased this one

[gromakovsky]

Can you please make history linear here?

[serhiip]

Rebased everything onto master

[gromakovsky]

Oh, and now the only remaining obstacle is this:

The base branch requires all commits to be signed.

[serhiip]

Oh c'mon

[gromakovsky]

Thanks for your patience.
