JuliaSyntax: allow exponent literals before .. (#62206)
Allow numeric literals with exponent parts to be followed by the ..
operator without being tokenized as invalid numeric constants. This
keeps malformed trailing decimal-point literals invalid while preserving
interval-operator syntax after decimal and hex float literals.
Fixes #62200
