Fails to Create RuntimePath on startup in v1.30.0(Works in v1.17.0)

[yanmxa]

I encountered an issue when trying to start an embedded PostgreSQL instance locally. The following error occurs:

failed to get embeddedPostgres: unable to extract postgres archive /Users/yanmeng/.embedded-postgres-go/embedded-postgres-binaries-darwin-arm64v8-16.4.0.txz to /Users/yanmeng/.embedded-postgres-go-17362/extracted, if running parallel tests, configure RuntimePath to isolate testing directories, stat /Users/yanmeng/.embedded-postgres-go-17362: no such file or directory

It seems that, starting from version v1.30.0, the RuntimePath is not being created if it doesn't already exist. This behavior differs from v1.17.0, where the RuntimePath was automatically created.

The script is:

		postgresDataPath = filepath.Join(postgresDataPath,
			fmt.Sprintf(".embedded-postgres-go-%d", postgresPort),
			"extracted")

		postgresConfig := embeddedpostgres.DefaultConfig().
			Port(postgresPort).
			RuntimePath(postgresDataPath).
			BinariesPath(postgresDataPath).
			DataPath(filepath.Join(postgresDataPath, "data")).
			Database("hoh")

		pg.embedded = embeddedpostgres.NewDatabase(postgresConfig)
		if err = pg.embedded.Start(); err != nil {
			fmt.Printf("failed to get embeddedPostgres: %s", err.Error())
			return pg, err
		}

Hey @yanmxa apologies for the delay here.

I've added coverage and proven this works here

embedded-postgres/embedded_postgres_test.go

Line 675 in 54b81a8

func Test_CustomRuntimePathCreatedWhenNotPresent(t *testing.T) {

I'll make a new release for this fix shortly.
