Replace 1024-bit RSA test key with 2048-bit key to eliminate InsecureKeyLengthWarning

[Copilot]

PyJWT raises InsecureKeyLengthWarning when using RSA keys below 2048 bits (NIST SP 800-131A minimum). The GoogleOneTapTest class was using a 1024-bit RSA key pair for JWT encoding/decoding tests.

Changes

• Generated new 2048-bit RSA key pair using OpenSSL
• Updated GoogleOneTapTest.private_key (PKCS#1 format)
• Updated GoogleOneTapTest.public_key (standard PEM format)

The new keys maintain the same format and structure as the original keys, ensuring test compatibility while meeting current security standards.

Original prompt

Update social_core/tests/backends/test_google.py to use modern RSA key for testing to avoid warnings:

social_core/tests/backends/test_google.py::GoogleOneTapTest::test_get_decoded_info_error
social_core/tests/backends/test_google.py::GoogleOneTapTest::test_get_decoded_info_success
  /home/runner/work/social-core/social-core/.tox/py310/lib/python3.10/site-packages/jwt/api_jwt.py:153: InsecureKeyLengthWarning: The RSA key is 1024 bits long, which is below the minimum recommended size of 2048 bits. See NIST SP 800-131A.
