Add autofix support for the form-method-require rule

[coliff]

Implemented autofix support for the form-method-require rule.

• ✅ Added createFormMethodRequireFix() function in htmlhint-server/src/server.ts
• ✅ Added the new rule to the autofix switch statement
• ✅ Updated README.md to document the new autofix support
• ✅ Compiled successfully with no errors

The autofix will add an empty method="" attribute, leaving the cursor positioned so users can easily fill in get, post, or dialog as needed.

Code Review

This pull request successfully implements autofix support for the form-method-require rule. The changes include adding the createFormMethodRequireFix function, integrating it into the autofix logic, and updating the CHANGELOG.md and README.md files. The implementation is well-done and handles edge cases correctly. I have one minor suggestion to improve code clarity by reducing a small amount of duplication. Overall, this is a valuable addition to the extension's autofix capabilities.

The newText variable is assigned the same value ' method=""' in both branches of the if-else statement. You can avoid this duplication by declaring and initializing newText as a constant before the conditional block. This improves code readability and maintainability by making it clear that the text to be inserted is always the same.

  // Calculate insertion position
  const newText = ' method=""';
  let insertPosition: number;

  if (existingAttrs.trim()) {
    // There are existing attributes, add method after them
    insertPosition = tagStart + beforeAttrs.length + existingAttrs.length;
  } else {
    // No existing attributes, add method right after "form"
    insertPosition = tagStart + beforeAttrs.length;
  }
