Compose Format Document rounds big numbers

[NLZ]

Let's say I have this (fake for the example) key-value in my compose.yaml:

environment:
  discord_id: 1147053346671102335

When I select Format Document it will round 1147053346671102335 to 1147053346671102300, which I don't think I need to explain why is bad.

Of course I can quote it to make into a string, but was blindsided by this behavior, would be nice to save others from it.

Good find. I'll transfer this to the compose language service repository.
