[TABJS-22] Remove singular `name` and `prefix` from response (deprecated)

[dtbuchholz]

The validator response now returns plural versions of names and prefixes instead of the singular forms. The singular definitions can be dropped. This will need some refactoring elsewhere too; see here for some related fixes needed:

• tableland-js/packages/sdk/src/registry/index.ts

  Line 39 in 29a84d6

  type CreateOneParams as CreateTableParams, // deprecated

• used here

  tableland-js/packages/sdk/src/registry/create.ts

  Line 27 in 29a84d6

  export async function prepareCreateOne({

• and here

  tableland-js/packages/sdk/src/lowlevel.ts

  Line 75 in 29a84d6

  // TODO: this only works if the transaction will only be affecting a single table.
