Remove opening times from webchat contact method
Remove opening times from webchat contact method

The current opening times of HMRC webchat are more flexible than 
suggested here. Sometimes webchat is open earlier or later in the day, 
and at times may be closed while advisors handle other channels.

As a result, these opening times can be misleading and lead to 
confusion.

We should remove these opening times until they become more stable.
