If TZInfo-data is not present in windows, let the user know.

Fixes #19175.
Rails tries calling TZInfo::DataSource.get. If it gets a DataSourceNotFound error then it prints out

Gem 'tzinfo-data' is not present. Please add gem 'tzinfo-data' to your Gemfile and run bundle install

I think we should use the Rails.logger here. Or even throw a warning instead.

[rafaelfranca]

We should just raise. We don't want the boot to continue.

If tzinfo-data not found, it aborts with the message "tzinfo-data' is not present. Please add gem 'tzinfo-data' to your Gemfile and run bundle install"

[arthurnn]

why the extra ' ?

[sivsushruth]

Typo, fixing it.
Thanks.

[arthurnn]

I also wonder if we can test this somehow..
Also if you could squash all commits in one, so we have a smaller history.
thanks

Re-raise the exception with a message.

rescue TZInfo::DataSourceNotFound => e
  raise e.exception "tzinfo-data is not present. Please add gem 'tzinfo-data' to your Gemfile and run bundle install"
end

[sivsushruth]

@arthurnn @rafaelfranca I chose to raise an exception instead of aborting directly because it would allow for users to rescue the error if they wanted.
Let me know what you think.

Thanks

@sivsushruth I like raising an error 👍 , I still think we should add a regression tests somewhere to make sure this works, and to make sure nobody removes this code.

@arthurnn @rafaelfranca I cant seem to figure out how/where to write tests for initializer . Any suggestions?

Thanks

[arthurnn]

I will merge this for now. We dont have windows only tests as far as I can tell, so it makes kinda harder to test this.
If anyone has any suggestion on how to add test to this, please ping me in the PR and add a reference to this.
thanks all
