Fix support for integer values in float/decimal type columns (#2205)

## Why make this change?

- Closes #1629
- Unable to cast object of type 'HotChocolate.Language.IntValueNode' to
type 'HotChocolate.Language.FloatValueNode', when using Integer values
for float/decimal/single column types

## What is this change?

- using `float.Parse()` and `decimal.Parse()` which automatically takes
care of int values.

## How was this tested?

- Added new test data points in the existing tests for
insertion/updation of float/decimal/single type columns with Integer
values
