Error on keyspaces starting with a number

[toptobes]

Got an issue from someone reporting that the Data API does not accept otherwise perfectly valid keyspaces which start with a number, such as 2DQJAUtSzzzKP9buDTvUvPk3. I can confirm that such a keyspace can be created from the portal with absolutely no issues.

I'm able to create a Keyspace both via REST API and Admin area with the value "2DQJAUtSzzzKP9buDTvUvPk3" but unable to retrieve and use it via the REST api.

const dbAdmin = admin.dbAdmin(dbEndpoint)
await dbAdmin.createKeyspace('2DQJAUtSzzzKP9buDTvUvPk3')

// then i can list: 
const keyspaces = await dbAdmin.listKeyspaces()
console.log(keyspaces)

{
  "existingKeyspaces": [
    "default_keyspace",
    "2DQJAUtSzzzKP9buDTvUvPk3"
  ]
}

Then when trying to use the keyspace:

const collectionNames = await db.listCollections({ nameOnly: true, keyspace: '2DQJAUtSzzzKP9buDTvUvPk3' })
// or 
await db.createCollection('collectionname', { keyspace: '2DQJAUtSzzzKP9buDTvUvPk3' })

This returns:

DataAPIResponseError: Request invalid: field 'keyspace' value "2DQJAUtSzzzKP9buDTvUvPk3" not valid. Problem: must match "[a-zA-Z][a-zA-Z0-9_]*".

Similar to #1674, will solve them together
