fix(create-mud): include .gitignore files in created projects

[tash-2s]

This Pull Request resolves #1865, where projects created by create-mud are missing .gitignore files, specifically in versions 2.0.0-next.13 and 2.0.0-next.14.

The cause is an update in npm-packlist, used during the npm package publishing process to list target package files. The MUD's release command changeset publish relies on npm-packlist through pnpm publish.

The previous version of npm-packlist included .gitignore files by respecting the .npmignore file, but the latest version doesn't. This change is not documented in its changelog, but based on this issue's comment, it seems better not to expect .gitignore files to be included.

This PR addresses this issue by utilizing create-create-app's feature for handling .gitignore. During the build process of create-mud, .gitignore files are renamed to gitignore, ensuring their inclusion in the package. When the create-mud cli is executed, create-create-app automatically renames those gitignore files back to .gitignore for project creation.

To test the fix, you can run pnpm build && dist/cli.js test-project.

Reference: #336

Testing the npm-packlist behavior:

To observe the behavior change in npm-packlist, we can use pnpm pack or npm pack without the changes from this PR.

$ cd packages/create-mud
$ pnpm build # copy template files to dist/

# with earlier version of pnpm (npm-packlist v5)
$ npm install -g [email protected] 
$ pnpm pack
$ tar -xzf create-mud-2.0.0-next.14.tgz # extract to package/
$ ls -A package/dist/templates/vanilla # .gitignore included
.eslintrc           .gitignore          mprocs.yaml         packages
.gitattributes      .vscode             package.json        pnpm-workspace.yaml
$ rm -r create-mud-2.0.0-next.14.tgz package

# with more recent version of pnpm (npm-packlist v8)
$ npm install -g [email protected]
$ pnpm pack
$ tar -xzf create-mud-2.0.0-next.14.tgz
$ ls -A package/dist/templates/vanilla # .gitignore not included
.eslintrc           .vscode             package.json        pnpm-workspace.yaml
.gitattributes      mprocs.yaml         packages
$ rm -r create-mud-2.0.0-next.14.tgz package

It seems that pnpm downgraded npm-packlist last week due to a performance issue, which means the latest version of pnpm includes the .gitignore files without this change. However, I believe this new approach is more stable.
