`.gap-px` utility is not merged with `.gap-1`

[Predota]

Describe the bug

The .gap-px utility is not merged with .gap-1 as expected when using tailwind-merge. Instead of resolving to a single gap utility, both classes remain, leading to potential styling conflicts.

To Reproduce

1. Use tailwind-merge to process a class list that includes both .gap-px and .gap-1.
2. Observe that both classes persist instead of .gap-1 taking precedence.

You can use the following CodeSandbox to reproduce the issue:

Expected behavior

The .gap-1 utility should replace .gap-px in the final merged class list since it has a higher numerical value.

Environment

• tailwind-merge version: 3.0.1
• Runtime: Node.js 18
• Bundler: Parcel 1.12.5
• TypeScript: 4.4.4
• Browser: [e.g. Chrome 120, Firefox 118]
