chore: wrap git api in try catch

[sayali10]

📝 Description

We want to trigger comparadise based on the event trigger in our application instead of git PR.
For that we will be using unique id from app instead of commit hash to store new images.

While trying to run comparadise using unique id instead of commit hash, I am getting this error because the commit hash is invalid:

/home/runners/actions-runner/_work/_actions/ExpediaGroup/comparadise/v1/action/dist/main.js:26313
      const error = new RequestError(toErrorMessage(data), status, {
                    ^
RequestError [HttpError]: Not Found - https://docs.github.com/rest/commits/statuses#list-commit-statuses-for-a-reference
    at /home/runners/actions-runner/_work/_actions/ExpediaGroup/comparadise/v1/action/dist/main.js:26313:21
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async getLatestVisualRegressionStatus (/home/runners/actions-runner/_work/_actions/ExpediaGroup/comparadise/v1/action/dist/main.js:36109:20)
    at async run (/home/runners/actions-runner/_work/_actions/ExpediaGroup/comparadise/v1/action/dist/main.js:36163:40) {
  status: 404,

This PR wraps that call in try catch and returns null on error.
This way we would be able to save the new/diff images using unique id from app instead of commit hash.

Moved it down just before the usage.

I wrapped it in common method so that we can print the error message => Failed to update commit status.
This would give little more clarity on reason why job failed.

[sayali10]

We are using optional chaining operator wherever we are using latestVisualRegressionStatus value so returning null shouldn't break anything.

As discussed, we are going to add a new "diff id" param that can be used in place of commit hash
