[Enhancement]: (Docs) Better Usage example for golang redis driver

Proposal

In the docs, usage is given:

redisContainer, err := tcredis.Run(ctx,
    "redis:7",
    tcredis.WithSnapshotting(10, 1),
    tcredis.WithLogLevel(tcredis.LogLevelVerbose),
    tcredis.WithConfigFile(filepath.Join("testdata", "redis7.conf")),

And when i copied and run that, i got this error as nature:

                Error Trace:    /home/muhammedkucukaslan/code/projects/advanced-todo-api/tests/utils.go:55
                                                        /home/muhammedkucukaslan/code/projects/advanced-todo-api/tests/e2e/todo/create_todo_handler_caching_test.go:61
                Error:          Received unexpected error:
                                generic container: create container: created hook: can't copy testdata/redis7.conf to container: open testdata/redis7.conf: no such file or directory
                Test:           TestCreateTodoHandlerCaching
                Messages:       failed to start Redis container
--- FAIL: TestCreateTodoHandlerCaching (3.24s)

Solution

I know that following docs are explaining that this is an optional config but it think it would be better to make it like bellow for faster quickstart:

redisContainer, err := tcredis.Run(context.Background(), "redis:7")

Start with the Redis module documentation at https://golang.testcontainers.org/modules/redis/ and review the current usage example. Update the quickstart to use the minimal Redis container invocation, while keeping the optional configuration details clear; done means the example can run without a missing testdata/redis7.conf file.
