Remove force new modifier on name attribute

[sebasslash]

Description

The issue was reported here.

Effectively, the ForceNew modifier was set in the name attribute of the r/tfe_team schema causing the recreation of the team resource whenever the name was updated.

This PR removes this as there isn't any API specific behavior that requires the team to be recreated upon a name change.

Testing plan

In order to smoke test this, we'll need a simple configuration that provisions a team (ensure your organization is not on the free tier):

resource "tfe_team" "foo" {
  name = "the-foo-fighters"
  organization = "rocknroll"
}

Create the team first using terraform apply and then simply modify the name, running terraform apply again. Overriding the provider to a local build including my changes, you should see that the team is no longer recreated.

It's always been possible to update a team name! 👍
