## Description
This PR ensures that the default prettier config is used for examples
and templates.
This config is compatible with `prettier@3` as well (upgrading prettier
is bigger change that can be a future PR).
## Changes
- Updated `.prettierrc.json` in root with `"trailingComma": "es5"` (will
be needed upgrading to prettier@3)
- Added `examples/.prettierrc.json` with default config (this will
change every example)
- Added `packages/create-next-app/templates/.prettierrc.json` with
default config (this will change every template)
## Related

- Closes#54409
### Reason for making this change
https://yarnpkg.com/getting-started/qa#:~:text=yarn%2Finstall%2Dstate.,your%20workspaces%20all%20over%20again.
In the official documentation of `yarn`, it is stated that `.yarn/install-state.gz` is an optimization file that developer shouldn't ever have to commit. However, currently, when running `create-next-app`, `.yarn/install-state.gz` is being commited.
### Remaining work
I apologize for only modifying one template initially to initiate the discussion first.
If this change is agreed upon, it should be synchronized with other `.gitignore` templates. Would it be possible to follow a similar approach as in https://github.com/vercel/next.js/pull/47241? I would appreciate any assistance in syncing this change.
They are added to `.gitignore` already. Follow-up on #39051

I added ` *.tsbuildinfo` to gitignores of examples that use typescript and don't already have it. By use typescript I mean have `tsconfig` somewhere in their directory tree.
I used the following script to update the files:
```bash
#!/bin/bash
set -eou pipefail
cd examples
examples=`git ls-files . | grep tsconfig | xargs dirname | grep -v "/"`
for example in $examples; do
if ! grep -q tsbuildinfo $example/.gitignore; then
gitignore="$example/.gitignore"
echo $gitignore
tail -c1 $gitignore | read -r _ || echo >> $gitignore
echo -e "\n# typescript\n*.tsbuildinfo" >> $gitignore
fi
done
```
This adds a new example under `cms-plasmic/`. It serves as a general-purpose example that should be able to work with any Plasmic project, which can be set via environment variables.
