preserve comments in package yaml

[mptr]

• I'd be willing to implement this feature (contributing guide)

It would be nice, if pnpm preserves comments placed in a package.yaml file.

Current behavior

package.yaml (pre install)

...
scripts:
  # just a test
  foo: echo bar
dependencies:
  ...

run pnpm install <dep>

package.yaml (post install)

...
scripts:
  foo: echo bar
dependencies:
  <dep>: <version>
  ...

Desired behavior

package.yaml (pre install)

...
scripts:
  # just a test
  foo: echo bar
dependencies:
  ...

run pnpm install <dep>

package.yaml (post install)

...
scripts:
  # just a test
  foo: echo bar
dependencies:
  <dep>: <version>
  ...
