Redundant curly braces in string template

Reports usages of curly braces in string templates around simple identifiers.

Use the 'Remove curly braces' quick-fix to remove the redundant braces.

Examples:

fun redundant() {
   val x = 4
   val y = "${x}" // <== redundant
}

fun correctUsage() {
    val x = "x"
    val y = "${x.length}" // <== Ok
}

After the quick-fix is applied:

fun redundant() {
   val x = 4
   val y = "$x"
}

fun correctUsage() {
    val x = "x" <== Updated
    val y = "${x.length}"
}
