No Support for python3.13 even though latest SAM CLI is installed

[dan-marra-ebrs]

I have a local lambda runtime configuration for a SAM template that contains a lambda using python3.13 runtime.
I can build with sam manually, but the toolkit give me the error:

Error: The runtime 'python3.13' is unsupported.

When making a new runtime configuration without using a template, I don't see 3.13 in the list of supported runtimes.

3.13 runtime has been available since November 2024. I can't tell if this is a bug on my end, or if support hasn't been added to the toolkit yet
