Volta update check through Github is not using GITHUB_COM_TOKEN env

How are you running Renovate?

Self-hosted

Please select which platform you are using if self-hosting.

GitLab self-hosted

26.14.0

Describe the bug

It seems that renovate is checking for updates of Nodejs without using the GITHUB_COM_TOKEN. If you have more than 60 projects, the rate limit is hit pretty fast. This might be related to #11496.
The logs clearly show "x-ratelimit-limit":"60" while that should be higher with a token.

I can verify that a token has been set though (stated in the logs):

{"hostRules":[{"hostType":"github","matchHost":"github.com","token":"***********"},

Setting the token in hostRules in the config instead of the env variable fixed this for me.
