facebookbusiness README says that Ruby v2 is sufficient but the gemspec says otherwise

[raymondweidner]

Which SDK version are you using?

• facebookbusiness v15.0.1
• ruby 2.7

What's the issue?

We want to upgrade to v16 or v17. The README says "We developed this SDK using Ruby 2.0, and supports Ruby 2.0+..." However, the gemspec has the following line:

s.required_ruby_version = '>= 3.0'

Our organization is currently on Ruby v2.7, and we are planning to upgrade to Ruby 3x in the next few quarters. However, v15 of facebookbusiness is slated for end-of-life on 2023-08-15. Upgrading our version of Ruby in that timeframe is not feasible.

Is Ruby v3 really necessary for facebookbusiness? If not, it would be great if the gemspec could be updated accordingly. If so, it would be a good idea to update the README.

Steps/Sample code to reproduce the issue

N/A

Observed Results:

Attempting to upgrade facebookbusiness to v17 yielded the following output:

% gem update facebookbusiness
Updating installed gems
Updating facebookbusiness
Fetching facebookbusiness-17.0.1.gem
ERROR:  Error installing facebookbusiness:
	There are no versions of facebookbusiness (= 17.0.1) compatible with your Ruby & RubyGems
	facebookbusiness requires Ruby version >= 3.0. The current ruby version is 2.7xxx.

Expected Results:

That it would have succeeded.

Thank you @raymondweidner we have recently updated our requirement to use Ruby 3.0+. We'll update the documentation to point this out. This commit (00e7668) updated the build environment.
