fix: keep package declaration with annotations before import declarations

[jtkiesel]

What changed with this PR:

Package declarations with multiple annotations are no longer moved after import declarations. This was actually caused by a bug with the tree-sitter Java grammar, which thinks the package declaration with multiple annotations is a local variable declaration, but it was easy enough to work around here.

Example

Input

@A
@B
package a;

import a.A;
import b.B;

Output

@A
@B
package a;

import a.A;
import b.B;
