Revert "PHP: Ensure up to date dependencies of the generated code"

[jedevc]

This reverts #9625 - looks like the PHP tests have started failing after it, not sure why.

Example failure: https://v3.dagger.cloud/dagger/traces/1e0e5e64a1c90d597a534d6e8a6faf82?span=1f0ea2d68e44a4e2&logs

The tests that are failing:

dagger/core/integration/module_php_test.go

Lines 18 to 31 in bf712c4

	t.Run("from upstream", func(ctx context.Context, t *testctx.T) {
	c := connect(ctx, t)
	modGen := c.Container().From(golangImage).
	WithMountedFile(testCLIBinPath, daggerCliFile(t, c)).
	WithWorkdir("/work").
	With(daggerExec("init", "--name=bare", "--sdk=github.com/dagger/dagger/sdk/php"))
	out, err := modGen.
	With(daggerQuery(`{bare{containerEcho(stringArg:"hello"){stdout}}}`)).
	Stdout(ctx)
	require.NoError(t, err)
	require.JSONEq(t, `{"bare":{"containerEcho":{"stdout":"hello\n"}}}`, out)
	})

These only started failing on main because these tests fetch the version of the PHP SDK from main. While these checks are somewhat important, we should probably have a test for the commit - similar to how it's done for TestJava.
