Consider adding no-template-curly-in-string rule

[McGiogen]

It is a common and easy mistake to write string templates with single quote char ' instead of backticks , especially when you are fixing a prefer-template` error, converting a string to template but forgetting about backticks.

Adding no-template-curly-in-string rule can help to find those errors.

Since I'm one of the ones that suggested that rule in the first place (eslint/eslint#5850 / eslint/eslint#6186 ), I'm definitely planning on enabling it prior to the next semver-major release. Our release process ensures that all rules are configured, so it will definitely be covered.
