Relative links in blog posts are broken

[mstenta]

@wotnak discovered that relative links in farmOS-community-blog posts are broken. Originally discovered in this PR comment: farmOS/farmOS-community-blog#25 (review)

I can confirm that the second link in this post on the live blog is also broken: https://farmos.org/blog/2024/farmOS-3.0.0/

In the post markdown, the link is to ../2023/farmOS-2.0.0, but in the HTML that is generated it leads to https://farmos.org/2023/farmOS-2.0.0 (without the /blog/).

@wotnak found a workaround:

Using post slugs instead of folder names in relative links seems to generate working links

For example, this works:

./2023/farmOS-2.0.0

But this does not:

../2023/farmOS-2.0.0

... despite the fact that the 2023 directory is in the parent directory.

We can work with that in mind for now, until we figure out how to fix this.
