fix(parser): no longer ignore whole block when prettier-ignore at start

[jtkiesel]

What changed with this PR:

When a block begins with // prettier-ignore, only the first statement is ignored, rather than the whole block.

Example

Input

package tech.jhipster;

import java.util.Map;

public class StrangePrettierIgnore {

  private StrangePrettierIgnore() {}

  public static void drinkBeers() {
    // prettier-ignore
    Map<String, String> beers = Map.of(
      "beer1", "Gulden Draak",
      "beer2", "Piraat",
      "beer3", "Kapittel"
    );

           System.out.println(beers); // not well formated here
  }
}

Output

package tech.jhipster;

import java.util.Map;

public class StrangePrettierIgnore {

  private StrangePrettierIgnore() {}

  public static void drinkBeers() {
    // prettier-ignore
    Map<String, String> beers = Map.of(
      "beer1", "Gulden Draak",
      "beer2", "Piraat",
      "beer3", "Kapittel"
    );

    System.out.println(beers); // not well formated here
  }
}

@clementdessoude This is a small PR that ought to be a relatively short review & relatively easy to get merged in. Let me know if you have any comments or concerns.

No worries at all, thanks for the review! To be honest I forgot about this one, and happened to see it again yesterday.
