Option to configure Tag Key TLL in Redis

Issue: Configurable TTL for Redis Tag Keys

Problem
The TTL (Time to Live) for Redis tag keys is currently hardcoded to 720*time.Hour (30 days). This results in excessive memory consumption in Redis instances, as tags persist far longer than the associated cached values (which have significantly shorter TTLs).

Current Implementation
The TTL is set to 30 days in the setTags function:

func (s *RedisStore) setTags(ctx context.Context, key any, tags []string) {
	for _, tag := range tags {
		tagKey := fmt.Sprintf(RedisTagPattern, tag)
		s.client.SAdd(ctx, tagKey, key.(string))
		s.client.Expire(ctx, tagKey, 720*time.Hour) // Hardcoded TTL
	}
}

Request
Add the ability to configure the TTL duration for Redis tag keys instead of using a hardcoded value.
