Introduce value alias for cacheNames in @⁠CacheConfig

Prior to this commit @⁠CacheConfig did not have a `value` attribute
alias for `cacheNames`, even though the rest of the cache-related
annotations (such as @⁠Cacheable, @⁠CachePut, etc.) do have a `value` /
`cacheNames` alias pair.

To address that inconsistency, this commit introduces a `value` alias
for `cacheNames` in @⁠CacheConfig as well.

See gh-35096
Closes gh-35152
