Describe the bug

aws ec2-instance-connect send-ssh-public-key incorrectly recognises the public key length as 27 bytes, when it is 256 bytes

SDK version number

2.0.8 per:

➜  networky git:(ec2-access) ✗ aws --version
aws-cli/2.0.8 Python/3.8.2 Darwin/19.4.0 botocore/2.0.0dev12

Platform/OS/Hardware/Device

Mac OS X Catalina

To Reproduce (observed behavior)

➜  networky git:(ec2-access) ✗ make connect-neptune-proxy
aws ec2-instance-connect send-ssh-public-key --instance-id i-0e5ad6adb8f5f3335 --availability-zone eu-west-2a --instance-os-user ec2-user --ssh-public-key ~/.ssh/id_rsa.pub

Parameter validation failed:
Invalid length for parameter SSHPublicKey, value: 27, valid range: 256-inf
make: *** [connect-neptune-proxy] Error 252
➜  networky git:(ec2-access) ✗ ssh-keygen -lf ~/.ssh/id_rsa.pub
2048 SHA256:wQzPTplSAB7p8rXGcOWxcbF/AOnYc4+bsmNaFcxAf9o [email protected] (RSA)

Expected behavior

I expect my public key to be successfully pushed to the EC2 instance.
