Slider property no longer accepts decimals

[sofietoft]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

14.3.0

Bug summary

The configuration for the Slider Property Editor in Umbraco CMS no longer works when configuring decimals as some or all of the values.
When adding decimals in the fields, the field will get a red outline indicating some kind of error. However, I am still able to save and submit the configuration without actually getting any errors.
The errors start when I use the Slider on a content item.

The JSON error I get, when trying to configure the Slider on content:

System.Text.Json.JsonException: The JSON value could not be converted to System.Int32. Path: $.from | LineNumber: 0 | BytePositionInLine: 11.
 ---> System.FormatException: Either the JSON value is not in a supported format, or is out of bounds for an Int32.

Now, this might be a bug, but it might also be intended behavior.

I've testing the latest version of Umbraco 13 as well, and here it is possible to use decimals in the configuration.

Steps to reproduce

1. Add a Slider Property to a Document Type i Umbraco 14.3.0
2. Apply the following configuration:

3. Save and submit the changes
4. Open a content item that uses the Document Type
5. Move the slider to a new position
6. Save (or try to) the content

Expected result / actual result

The expected outcome would be that it saves without errors.
That is unfortunately not the case.
