Describe the bug

Version: 16.0.0

To Reproduce

getExpressionOrThrow no longer exists on JsxElement in v16. This doesn't appear to be present in the release notes for the 16.0.0 breaking changes

import { SyntaxKind, JsxAttribute } from 'ts-morph'

function doJsxThing(n: JsxAttribute) {
  const initializer = n.getInitializerOrThrow()
  if (initializer.isKind(SyntaxKind.StringLiteral)) {
    return
  }
  // no longer compiles
  const expression = initializer.getExpressionOrThrow()
}

Expected behavior

I think the code should compile if this isn't an expected change. Otherwise would appreciate an alternative!
