chore: exclude .pnpm-store from Docker build context

[samtheruby]

Description

On local builds the .pnpm-store directory is not excluded from the build context. Since it's never referenced by the Dockerfile RUN --mount=type=cache uses its own in-container store path, and it gets shipped to the daemon on every build for no benefit. Adding .pnpm-store to .dockerignore cuts build context size by over 1gb with no change to build output.

How Has This Been Tested?

Local Docker build was run successfully with image output size reduced by 1.2gb

Poem

A bunny tucked the store away,
Safe from Docker’s busy day.
No pnpm fluff shall cross the gate,
Builds stay tidy, small, and great!

Hello,

What does the pnpm store path command return? By default from what I read, it should not be in the seerr folder unless you explicitly configured it to be there.

Generally, you are right and on any CI build or even a lot of local builds .pnpm-store should not be carried over, however since my home folder and project folder live on different disks/volumes, pnpm can't hardlink the files properly, so it falls back to putting the store inside the project folder instead. Whether it's worth fixing a niche case is a different matter, but either way I don't think there is any downside to explicitly excluding .pnpm-store so it's never copied over.

pnpm store path returns /mnt/user/<share name>/docker-build/seerr/.pnpm-store/v11
