Fix NUMBER field update issue by converting string values to numbers

[Copilot]

This PR fixes an issue where NUMBER field types could not be updated because string values from GitHub Actions inputs were being passed directly to the GraphQL API, which expects numeric values.

Problem

When updating a NUMBER field with a value like 0, the GitHub Actions input system provides the value as a string "0". The existing code passed this string directly to the GraphQL mutation, but the API expects a numeric value for NUMBER fields, causing the update to fail.

# This workflow would fail to update NUMBER fields
- name: Update field value
  uses: github/update-project-action@v3
  with:
    field: my_number_field
    value: 0  # Becomes string "0" internally

Solution

Added type conversion logic to properly handle NUMBER fields:

1. New convertValueToFieldType() function - Converts string inputs to the appropriate type based on the field type:

   • NUMBER fields: Converts strings like "0", "42", "3.14" to numeric values
   • Other fields: Returns the original string value unchanged

2. Updated updateField() function - Now uses converted values instead of raw string inputs for all non-single-select fields

3. Comprehensive test coverage - Added tests for various number formats including the specific case mentioned in the issue

Testing

The fix includes tests for:

• Converting string "0" to numeric 0 (the exact case from the issue)
• Converting integer and float strings to numbers
• Error handling for invalid number strings
• Ensuring existing functionality for TEXT, DATE, and SINGLE_SELECT fields remains unchanged

All existing tests continue to pass, ensuring backward compatibility.

Fixes #171.
