`ctx.Request().RequestURI()` leads to high cardinality metric

8

The value of `path` changed from `ctx.Route().Path` to `string(ctx.Request().RequestURI())` in commit https://github.com/ansrivas/fiberprometheus/commit/bfc9e019f80791a79e0f780e92d26fa93a3f2d31. For route `/n/:id`, it will create metric for each unique id, instead of grouping them under `/n/:id`.
