Adjust project settings CI_JOB_TOKEN section wording

What does this MR do and why?

Context

This MR contains the changes from Rename "Limit access to this project" to "Allow... (!151704 - merged) (which was reverted because the language didn't match how the toggle works)...

except the toggle label will remain "Limit access _to_ this project" to match how the feature currently works:

• toggle off: any project can use CI_JOB_TOKEN to authenticate with this project
• toggle on: only projects on the allowlist can use CI_JOB_TOKEN to authenticate with this project

How to set up and validate locally

1. navigate to a project
2. in the sidebar, choose Settings => CI/CD
3. expand the Job token permissions section (formerly known as Token Access)
4. review the following text changes:

settings section
  title:
-   Token Access
+   Job token permissions
  description:
-   Control how the CI_JOB_TOKEN CI/CD variable is used for API access between projects.
+   Control whether CI/CD job tokens can be used to authenticate with this project.

toggle
  help text:
-   Allow access to this project from authorized groups or projects by adding them to the allowlist. It is a security risk to disable this feature, because unauthorized projects might attempt to retrieve an active token and access the API.
+   When enabled, only groups and projects in the allowlist are authorized to use a CI/CD job token to authenticate requests to this project. When disabled, any group or project can do so.

card/table header
  title:
-   Groups and projects with access
+   Authorized groups and projects
  description (new)
+   Ensure only groups and projects with members authorized to access sensitive project data are added to the allowlist.
