fix: 🐛 Fix issue with setting 0 or false values

The change involves replacing the logical OR operator (`||`) with the
nullish coalescing operator (`??`) in the `_applyUniforms()` method.
This modification addresses a specific issue where 0 or false values
were not being correctly assigned. By using the nullish coalescing
operator, the code ensures that if the value of `this.uniforms[name]` is
either 0 or false, it will be properly assigned as the value for
`value`. This change enhances the accuracy and reliability of the code
by handling these specific cases effectively.

✅ Closes: #1741
