feat: add GitHub PR template

📚 Description

The number of repositories managed by Nuxt organizations is increasing day by day, and I think the cost of managing the repositories is on the rise.
I often see PRs that add GitHub PR templates to each repository for repository operation, but I think this can be solved by placing them in nuxt/.github.

• https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/creating-a-default-community-health-file

The behavior that occurs in each repository is as follows.

.github/pull_request_template.md has been placed

The pull_request_template.md set in each repository will take priority.

If a repository has any files in its own .github/ISSUE_TEMPLATE folder, including issue templates or a config.yml file, none of the contents of the default .github/ISSUE_TEMPLATE folder will be used.

.github/pull_request_template.md has not been placed

The pull_request_template.md in this repository will be used when creating a PR.

✍️ Note

• Only the GitHub PR template is added in this PR. The GitHub Issue template will be added in a separate PR.
• If there are no issues with this PR, we will take the same steps in the Nuxt modules organization.

My opinion...

I often use the previous ❓ Type of change item.
So I think it's fine for it to exist.

Thank you for always reviewing.

I would be happy to add back the 'type of change' section too.
