In order to improve the user experience with URLs for sections of the
Validation chapter, this commit makes the following changes to page
names in the "validation" folder.
- beans-beans.html --> data-binding.html
- conversion.html --> error-code-resolution.html
Some of the section anchors in data-binding.html have also been
renamed. For example, #beans-beans is now #data-binding-property-binding.
Closes gh-35181
