chore: Set version of pnpm

[kulla]

I personally use asdf to manage the versions of tools in my projects. With the .tool-versions it is possible to pin the version of pnpm with asdf. I have used the version mentioned in

loro-prosemirror/package.json

Line 5 in b2bcee5

"packageManager": "pnpm@10.19.0",

An alternative would be to add .tool-versions in .gitignore which I would also be happy about.

Pull request overview

This PR adds an .tool-versions file to enable asdf tool version manager support for pinning the pnpm version used in the project. The version specified (10.19.0) matches the existing packageManager field in package.json, ensuring consistency across different development environment management tools.

Key Changes:

• Added .tool-versions file specifying pnpm version 10.19.0

Hi there! You can easily add .tool-versions to a global .gitignore. For instance, you can run the following command in the shell:

echo '**/loro-prosemirror/.tool-versions' > ~/.gitignore_global
git config --global core.excludesFiles ~/.gitignore_global

After that, if you clone github.com/loro-dev/loro-prosemirror into a directory named loro-prosemirror, git will automatically ignore the .tool-versions file within it.

Thx for the clarification. I wanted to know whether you would like to make changes in the repo. I'll update my .git/info/exclude then.
