Use links to latest hackage doc pages

[muzimuzhi]

Unless the material need to stick to specific version of GHC/haskell package, I think it's preferable to use general links which will redirect to latest version of hackage doc pages.

For example, current link

<a href="http://hackage.haskell.org/package/base-4.12.0.0/docs/src/GHC.Base.html#map">Here’s map</a>

suggested link (https used)

<a href="https://hackage.haskell.org/package/base/docs/src/GHC.Base.html#map">Here’s map</a>

which will redirect to doc page for the latest base-4.14.1.0.

6 such links are found in part1.html:

$ grep -rno 'https\?://hackage\.haskell\.org/package/[a-xA-Z]\+-.*\.html' part1.html

Hi and thanks for the report! I'm intentionally trying to link to the versions of packages that the tests use. This (currently) means the Stack lts-14.9 snapshot.

got it. Many Thanks for the nice course, and look forward to the part 2.
