Quotes achieved general availability status

After collecting feedback during the beta phase, we have moved Quotes out of beta. The status of the following features has been changed to general availability:

• Creating Quote Requests.
• Creating Staged Quotes with the ability to modify discounts, product quantity, expiration date, and add a note to the Buyer.
• Creating a Quote from a Staged Quote as the offer the Seller makes to the Buyer.
• Creating an Order from a Quote.
• Renegotiation of a Quote between the Buyer and Seller.

In addition, we've also removed the Failed value from the QuoteState and MyQuoteState enums, as it is an unused value that the API does not return.

Changes:

• [API] Removed Failed value from QuoteState enum.
• [API] Removed Failed value from MyQuoteState enum.
• [GraphQL API] Changed the QuoteState type:
  • Enum value Failed was removed from enum QuoteState
• [GraphQL API] Changed the MyQuoteState type:
  • Enum value Failed was removed from enum MyQuoteState

The following changes were introduced in terms of GraphQL SDL:

enum QuoteState {
  Accepted
  Declined
  DeclinedForRenegotiation
  Pending
  RenegotiationAddressed
  Withdrawn
}

enum MyQuoteState {
