feat: map job check run id from default context variables to environment variable

[calvinbayer]

What does this PR do?

• Map the job's numeric id from Github Action's default context variables to an environment variable that can be picked up by the tracers

Motivation

• For some reason, the Github team decided to expose the numeric job id - which is the only means to uniquely identify a job - through the context variables and not the environment variables
• For the customers that use auto-instrumentation, we can map the variable for them, so they get accurate @ci.job.url and @ci.job.id tags on their test events out of the box. This enables easier navigation and correlation between CI Visibility and Test Optimization jobs
