Fix timeoutouts for large file downloads

[meain]

We have currently set the the timeout for large file downloads to a large value(48 hours) instead of setting it to a 0 value(which would be ideal). This is because when we set the timeout to 0, kiota sets the context with deadline of 0s into the future. This will need an upstream fix microsoft/kiota-http-go#76 .

	// FIXME: This should ideally be 0, but if we set to 0, graph
	// client with automatically set the context timeout to 0 as
	// well which will make the client unusable.
