fix: IsLongitude & IsLatitude missing input type number

[Juliencd]

Description

Both functions isLatitude and isLatitude should support number as input type like the documentation mentions it.

Checks if the string or number is a valid latitude coordinate.

Actual behavior

export function isLatitude(value: string): boolean {
  return (typeof value === 'number' || typeof value === 'string') && isLatLong(`${value},0`);
}

Expected behavior

export function isLatitude(value: number | string): boolean {
  return (typeof value === 'number' || typeof value === 'string') && isLatLong(`${value},0`);
}
