(pr-linter-exemption-labeler): the pr-linter-exemption-labeler action fails because of an older node version

[sakurai-ryo]

Describe the bug

Hi team.
Sometimes, the pr-linter-exemption-labeler fails to execute because of an older version of Node.js.
As a result, the pr-linter/exemption-requested label is not attached when an Exemption Request is submited in PR.

For example
#30210
https://github.com/aws/aws-cdk/actions/runs/9098051208/job/25007366324

The error that occurs is described in the octokit.js README as occurring in cases where Node.js v18 or higher is not used.

fetch is not set. Please pass a fetch implementation as new Octokit({ request: { fetch }}). Learn more at https://github.com/octokit/octokit.js/#fetch-missing

We are currently on v16. Is it possible to bump up to v18 or higher?
https://github.com/cdklabs/pr-linter-exemption-labeler/blob/main/action.yml

Expected Behavior

The pr-linter/exemption-requested label is correctly attached to the PR.

Current Behavior

The pr-linter/exemption-requested label is not attached when submitting an Exemption Request.

Reproduction Steps

Create a PR and submit an Exemption Request.

Per https://github.com/octokit/octokit.js/#fetch-missing, Octokit requires Node 18 or higher, which includes a native fetch API.

Needs review with the team.
