Update client for v1.12

[coszio]

Updates the client with the latest proto definitions, by following the contributing guide. Everything went smoothly 🏄

• Adds sanity tests for the new facet and distance matrix endpoints
• No new OneOf's to add manual helpers. The only new ones are only used for response types.

LGTM 🙏🙏

Example usage of the new endpoints:

SearchMatrixOffsets

import (
	"context"

	"github.com/qdrant/go-client/qdrant"
)

client, err := qdrant.NewClient(&qdrant.Config{
	Host: "localhost",
	Port: 6334,
})

sample := uint64(10)
limit := uint64(10)
res, err := client.SearchMatrixOffsets(context.Background(), &qdrant.SearchMatrixPoints{
	CollectionName: "{collection_name}",
	Sample:         &sample,
	Limit:          &limit,
})

SearchMatrixPairs

import (
	"context"

	"github.com/qdrant/go-client/qdrant"
)

client, err := qdrant.NewClient(&qdrant.Config{
	Host: "localhost",
	Port: 6334,
})

sample := uint64(10)
limit := uint64(10)
res, err := client.SearchMatrixPairs(context.Background(), &qdrant.SearchMatrixPoints{
	CollectionName: "{collection_name}",
	Sample:         &sample,
	Limit:          &limit,
})

Facet

import (
	"context"

	"github.com/qdrant/go-client/qdrant"
)

client, err := qdrant.NewClient(&qdrant.Config{
	Host: "localhost",
	Port: 6334,
})

res, err := client.Facet(context.Background(), &qdrant.FacetCounts{
	CollectionName: "{collection_name}",
	Key:            "key",
})

don't seem to be used in facet

sample := uint64(10)
limit := uint64(10)

Sorry, too much copy paste
