Referring the Github PAT from another file

[sjm-ho]

Hey, so I am deploying my arc runners on kubernetes, and for authenticating to github api I am using PAT tokens, now the directory I am in, I wish to commit it to github.

Is there a way I can refer the PAT value to values.yaml file, specifically in:

githubConfigSecret:
github_token: "my_pat_token"

where I have stored the PAT value in a txt file.

I am planning to add that txt file to .gitignore.
