refactor!: Pass the Teams body types by value and rename them to ...Request

[JamBalaya56562]

Updates #3644

This converts the three TeamsService body types, removing 6 entries from the paramcheck exception lists in .golangci.yml (3 from body-allowed-pointer-types and 3 from body-allowed-wrong-names), plus the 2 structfield allowed-tag-types entries marked # TODO: Teams.

Old	New	Methods
TeamAddTeamMembershipOptions	AddTeamMembershipRequest	AddTeamMembershipByID, AddTeamMembershipBySlug
TeamAddTeamRepoOptions	AddTeamRepoRequest	AddTeamRepoByID, AddTeamRepoBySlug
TeamProjectOptions	AddTeamProjectRequest	AddTeamProjectByID, AddTeamProjectBySlug

The first commit makes TeamAddTeamMembershipOptions.Role and TeamAddTeamRepoOptions.Permission *string, which clears the two # TODO: Teams entries in structfield's allowed-tag-types. Both properties are optional in the OpenAPI request schemas (neither schema has a required list), and TeamProjectOptions.Permission was already *string.

The method names are kept as Add...: the docs titles are "Add or update ...", and Add already matches the verb these methods have always used.

BREAKING CHANGE: TeamAddTeamMembershipOptions, TeamAddTeamRepoOptions and TeamProjectOptions are renamed to AddTeamMembershipRequest, AddTeamRepoRequest and AddTeamProjectRequest; TeamsService.AddTeamMembershipByID, AddTeamMembershipBySlug, AddTeamRepoByID, AddTeamRepoBySlug, AddTeamProjectByID and AddTeamProjectBySlug now take them by value instead of by pointer; AddTeamMembershipRequest.Role and AddTeamRepoRequest.Permission are now *string.
