Emitter inserts blank lines between all tags, including @param

According to the readme, @param and @returns should go together in a group like so:

  /**
   * Returns the average of two numbers.
   *
   * @remarks
   * This method is part of the {@link core-library#Statistics | Statistics subsystem}.
   *
   * @param x - The first input number
   * @param y - The second input number
   * @returns The arithmetic mean of `x` and `y`
   *
   * @beta
   */

When this comment is parsed and emitted by the emitter, blank lines are inserted between all the tags, including the @param and @returns tag:

/**
 * Returns the average of two numbers.
 *
 * @remarks
 *
 * This method is part of the {@link core-library#Statistics | Statistics subsystem}.
 *
 * @param x - The first input number
 *
 * @param y - The second input number
 *
 * @returns The arithmetic mean of `x` and `y`
 *
 * @beta
 */

These should be output as a group (or at least have an option to output them as a group).

Start with the README example and trace the emitter path that formats parsed doc comments. Compare its output for the @param and @returns tags with the documented grouping, then add coverage showing that related tags are emitted without blank lines between them.
