SchemaForm Input always a string

[liruohrh]

Is your enhancement request related to a problem? Please describe

The value of the Input.tsx component in ui/src/components/SchemaForm/components/ is always a string. When writing custom plugin configuration objects, numeric properties fail to work as expected, only string properties are valid.

Describe the solution you'd like

Automatically convert the value to a number when it should be a numeric type.
Maybe It is a break change, so I submit a issue but not pr.

Describe alternatives you've considered

In HTML, even if the type of is set to number, the value obtained through evt.target.value is still a string. This is because the value attribute of an HTML input element always returns the user's input as a string.

Currently for numeric types, a forced conversion is required during saving, for example, Number(evt.target.value is still a string, not a number type?);

Additionally, I will add forced conversion for the value based on the input's type attribute in the next version.
