Warn when JSX key attribute is "SyntaxKind.ConditionalExpression"

[trevorharwell]

🐛 Bug Report

If you specify the key attribute as a conditional key={condition ? "key1" : "key2"}, no warning is logged.

To Reproduce

<Trans i18nKey={someCondition ? "key1" : "key"} />

Expected behavior

I don't expect that the values of that condition would be resolved but just that a warning would be logged. I have "failOnWarnings" set to true and I would want to make sure no one on my team ever did this.

FYI I am happy to submit a PR for this. Starting with an issue per the contribution guidelines.

Also, if you do want me to submit a PR, would you prefer I add SyntaxKind.ConditionalExpression here https://github.com/i18next/i18next-parser/blob/master/src/lexers/jsx-lexer.js#L82 or change that to log a warning if any value is not a SyntaxKing.StringLiteral?
