This update addresses an issue in the mutation diff calculation
algorithm used during read repair. Previously, the algorithm used
`token` as the hashmap key. Since `token` is calculated basing on the
Murmur3 hash function, it could generate duplicate values for different
partition keys, causing corruption in the affected rows' values.

Since the issue affects all the relevant scylla versions, backport to: 6.1, 6.2
Closesscylladb/scylladb#21996
* github.com:scylladb/scylladb:
storage_proxy/read_repair: Remove redundant 'schema' parameter from `data_read_resolver::resolve` function.
storage_proxy/read_repair: Use `partition_key` instead of `token` key for mutation diff calculation hashmap.
test: Add test case for checking read repair diff calculation when having conflicting keys.
