Investigate our approach to error tolerance

[egiurleo]

• Sorbet already has some parser tests that capture their desired behavior
• The Sorbet team at Stripe said they don't care that the error messages are exactly the same, just that we report similar errors in all the same situations
• They also care about error and autocorrect locations, so if you see anything weird about locations, that's definitely something we have to fix!
• Types of errors in Prism
