fix(actions): do not require the get-disk-name job for forks

[gustavovalverde]

Motivation

Some PRs can't be merged as a new job was added which requires acccess to variables are not available from a fork repo, for example:

• add pub functionality for zaino #8964

Solution

• Add this job to the .patch-external.yml workflow
• This job was also missing from the .patch.yml which could cause issue in other instances not related to forks

Follow-up Work

Allow external PRs to be tested without avoiding to run these jobs
