[#182] Local github page deployment fails on Ruby >=3.0

[Eclipse-Dominator]

Fixes #182

Running bundle exec jekyll serve to test GitHub page deployment will fail due to a compatibility issue with Jekyll 3 and Ruby >=3.0.

Let's resolve this by

• adding "webrick" to Gemfile
• updating the relevant packages

No further comments on the fix but a couple of questions, mostly out of curiosity.

• Why does adding webricks fix the problem?
• How did you decide those packages need to be upgraded to those exact versions?

[Eclipse-Dominator]

I think prior to ruby 3.0, "webricks" package is installed by default. That's why after ruby 3.0, jekyll server will fail since they can no longer find the webricks package.

I think those were the version numbers after I updated ruby packages. I think I can fine tune the versions more? Alternatively, just removing gem.lock file and let the users install the latest version will work as well

[damithc]

I have no further comments on this PR. I also don't know enough about Jekyll to decide whether we should keep gem.lock in the repo or remove it. @se-edu/tech-team-level1 feel free to weigh in.

Thanks for the fix @Eclipse-Dominator Note that I edited the commit message slightly, to explain the reason for the crash so that the reason for the change is evident.
