Tracking issue for `noZeroFractions`

[coderabbitai]

Overview

This issue tracks the work needed to extend the noZeroFractions lint rule — currently implemented for JavaScript/TypeScript — to other languages where trailing zeros in numeric literals are also redundant.

Originally discussed in #9817.

TODO

• CSS: Implement a CSS version of noZeroFractions. Stylelint has a comparable rule: number-no-trailing-zeros.
• JSON: Implement a JSON version of noZeroFractions. Trailing zeros in JSON numeric values (e.g. 1.0) are redundant and can be simplified to 1.

Out of scope

• GraphQL: GraphQL distinguishes between float and integer types — 1.0 is a Float while 1 is an Int, so removing trailing zeros would change semantics. This rule should not be applied to GraphQL.
