do keyword and close bracket matching

[Marat Amerov]

reproduce:
go to do keyword in line 1; press %

code sample:

context 'webhooks' do
  before { allow_any_instance_of(described_class).to receive(:webhook_endpoint_active?).and_return(true) }

  it 'runs webhooks' do
    expect(Webhook::Runner).to receive(:deliver)
    subject
  end
end

it is ok without https://github.com/andymass/vim-matchup plugin.
