Adding IncludeEmailInRedirect field for email templates

[willvedd]

Description

This PR adds the includeEmailInRedirect boolean field for email templates. This comes per a request in the Terraform provider.

Additionally, included are some minor testing changes to the email templates testing to improve assertions and repeatability. These testing changes are only somewhat related to the core change here, but somewhat messy to separate while ensuring testing on this feature; willing to separate if requested.

Only change is here.

Deleting the email provider is necessary for repeatability. Otherwise, this will fail with a 409 when attempting to instantiate an email provider in givenAnEmailProvider(t) when one already exists.

I chose to run in this test only to limit the blast radius of the change, but it may also reside in the givenAnEmailProvider helper function to help ensure the repeatability of other tests too.

Suggested change

	err := m.Email.Delete()
	assert.NoError(t, err)

The email provider already gets deleted after the test: line 78 calls "givenAnEmailProvider" which calls the delete after the test:

go-auth0/management/email_test.go

Lines 109 to 111 in bcd755a

	t.Cleanup(func() {
	cleanupEmailProvider(t)
	})

That works before the test, but if an email provider already exists, it also needs to occur before a test is run. Otherwise it will perpetually fail.

t.Cleanup() registers a function to be called when the test finishes, which means the email provider will get deleted after the tests either passes or fails. So when we restart the test, there won't be any email provider to delete, as it was already deleted. :)

Ah, I think I get your point now. Let's do it differently tho, let's modify the givenAnEmailProvider() func to not error if there's already an email provider, but use that instead. Wdyt?

Adding actual assertions that the replaced template is as expected.
