time mismatch on entry page and introduction

[cmeesters]

Currently, the entry page displays a "short cut" to the introduction followed by -- 1 min. When following this link, we find a chapter title The Catalog and beneath Estimated reading time: 5 minutes..

Of course, reading time is highly subjective. I read the entry text in about 2.5 min (because I knew some things?) in a train (which slowed the process a bit). This is hard to estimate. Yet, displaying ~ 5 min at both places might be appropriate. Don't you think?

Totally! I will fix this together with some other bugs that might show up now, after the relaunch.

I just collect some other minor things in this issue, no need to make a bunch of separate ones:

• change reading time estimate to be same on index and actual page
• add links to github page from individual wf pages
• the note on the 'The catalog' landing page does not display correctly (Use the --dry-run option first to check if all inputs are found)
