Add more constraints to the gemfile

This maintains compatibility with Ruby 3.3.5

@HereAround can you check if this works on your machine, i.e., that it does not break compatibility with an older version of ruby ? (I assume if you don't need these changes to run jekyll serve, you are on Ruby 3.2 ?)

When I executed bundle exec jekyll serve, it lead to the following error:

Could not find gem 'sassc (= 2.1.0)' in locally installed gems.

The source contains the following gems matching 'sassc':
  * sassc-2.4.0
Run `bundle install` to install missing gems.

So I executed bundle install:

Fetching gem metadata from https://rubygems.org/...........
Resolving dependencies...
Fetching logger 1.4.2
Fetching sassc 2.1.0 (x86_64-linux) (was 2.4.0)
Installing logger 1.4.2
Installing sassc 2.1.0 (x86_64-linux) (was 2.4.0)
Bundle complete! 8 Gemfile dependencies, 34 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

After this, bundle exec jekyll serve completes successfully and builds the website for me. Sadly though, jekyll serve - which I found very convenient - does not function any more after this change. (But this might not be the most important thing in the world.)

Long story short: I first had to install/update some packages on my machine. Only after that, jekyll could build the website on my system/machine.

My ruby version:

This is interesting: sassc 2.4 causes it to not build on my environment, but downgrading it to 2.1 (which makes it possible to build on my machine) requires you to do a bundle exec...
