docs: Help update Jekyll

[muromtsev]

Hi. There is a repository with a blog. So, recently I started to swear at what needs to be updated Jekyll.
How to do it?

Run bundle update in your terminal to update all outdated gems in your project.
Run bundle update jekyll in your terminal to just update Jekyll.

@muromtsev Most of the times, you just need to run bundle update.

See https://bundler.io/v2.0/man/bundle-update.1.html if you want to know more.

Be aware that the corresponding update will depend on the versions declared in your Gemfile:

gem "jekyll", "3.8.5" # stick to a specific version
gem "jekyll" # versionless, will update to latest version
gem "jekyll", ">= 3.7" # optimistic
gem "jekyll", "~>3" # pessimistic, don't upgrade to next major version, that might break compatibility

See https://guides.rubygems.org/patterns/#pessimistic-version-constraint to learn about semantic versioning and version constraint.

@jekyll/documentation Should we add a section on updating gems? (even if there's nothing specific to Jekyll)
