Align Jakarta Validation specification URL with standard naming convention

[otaviojava]

Currently, most Jakarta EE specifications follow a consistent and concise URL pattern under:

https://jakarta.ee/specifications/{spec-name}/

For example:

• Jakarta Data
  https://jakarta.ee/specifications/data/

• Jakarta NoSQL
  https://jakarta.ee/specifications/nosql/

However, Jakarta Validation diverges from this convention and is currently published under:

https://jakarta.ee/specifications/bean-validation/

This URL is inconsistent with:

• The short, domain-oriented naming used by other specifications
• The commonly used specification name (“Jakarta Validation”)
• Developer expectations when navigating the Jakarta EE specifications

Proposal

Rename (or alias) the Jakarta Validation specification URL to follow the same standard as the others, for example:

https://jakarta.ee/specifications/validation/
