fix links to relative instead of absolute ones

[lukaszstolarczuk]

quick grep on all 'https://pmem.io/' links and replace to '/' where it made sense;
Only links generated by hugo can be replaced in that way.

It makes more sense to use it that way, so you can use this website
locally and still test all links.

I could, but this is not as trivial as it was with Jekyll. I was thinking how to enable this generically for all users, but with no good solution yet.

What you can do is clone my fork and run within the repo:

hugo
hugo server

and you'll get a localhost version of it with no additional changes.

I tested some of the new links and they all worked fine.

Change your fork's gh page source to gh-pages and it should just work. The issue will be that relative links will resolve to pmem.io/... instead of myfork.github.io/... because the base URL is a parameter in the config, not something retrieved dynamically. To resolve that, I think we could set the base URL at build time (see rstudio/blogdown#412) where we could use e.g., fork name or a secret variable set to the proper domain. But I didn't have the time to do that yet.

ok, cool, there's some solution for that.
BTW, there's also a simple trick for CName: https://github.com/peaceiris/actions-gh-pages#%EF%B8%8F-add-cname-file-cname

Anyhow, thanks @pbalcer, I forgot we deploy this into gh-pages, fixed now on my fork: https://lukaszstolarczuk.github.io

I've updated this PR with some more links and it's ready for review.

I won't be doing the aforementioned updates/upgrades to the "deploy system".
