Bug: cannot use two separate github accounts for github-webhooks

[BentEngbers]

Thanks for making this awesome bot!!!

Describe the bug

When I use one instance of go-neb with a configuration file In a container, I cannot seem to get github webhooks working, with two seperate github accounts.

To Reproduce
Steps to reproduce the behavior:

configure github

1. create personal access tokens for two seperate github accounts.

configure go-neb

2. create one github realm (i tried creating two realms, one for each account).
3. add the personal access tokens to two seperate sessions (with two different "real" user ids in my case).
4. Create two github-webhook services, and add the correct repo to the correct github realm
5. (Optional) create an echo service, to test the bot
6. the github-webhook will work for one of the two accounts, but not for both at the same time.
7. (Optional) uncomment each of the users seperately to test their own config (both configs seperately work for me).

Expected behavior

I expect both github-webhooks for two github users to work in one go-neb instance.
