[FEAT]: Add data.github_team summary_only flag

[alexlo03]

Describe the need

The data source "github_team" should support summary_only flag similar to data source "organization_teams"
https://registry.terraform.io/providers/integrations/github/latest/docs/data-sources/organization_teams#summary_only

The github_team source downloads all the members and repos associated with the team, which makes it take O(minutes) whereas getting github_organization_teams takes O(seconds)

Here is where github_team source downloads all the members and repos:

terraform-provider-github/github/data_source_github_team.go

Line 83 in bb0f993

if d.Get("membership_type").(string) == "all" {

Example:

# Define a repo, give a bunch of teams access by name (teams defined by IDP)

resource "github_repository" "default" {
# ...
}

locals = {
  # team slugs
  teams = ["team-one", "team-two", ...]
}

data "github_team" "the_team" {
  for_each = local.teams
  slug     = each.key
}

resource "github_team_repository" "team_repo" {
  for_each = local.teams

  team_id    = data.github_team.team[each.key].id

  repository = github_repository.default.name
  permission = ...
}

If you are struggling with this, we are working around by doing

# Define a repo, give a bunch of teams access by name (teams defined by IDP)

resource "github_repository" "default" {
# ...
}

locals = {
  # team slugs
  teams = ["team-one", "team-two", ...]
}

# Rather than download the teams needed, download all teams in summary_only view
data "github_organization_teams" "all" {
  summary_only = "true"
}

resource "github_team_repository" "team_repo" {
  for_each = {
    for team in data.github_organization_teams.all.teams
  : team.slug => team.id if contains(keys(local.teams), team.slug) }

  team_id    = data.github_team.team[each.key].id

  repository = github_repository.default.name
  permission = ...
}
