"conda project add" completely override project files

[JeanChristopheMorinPerso]

Let's say I have a project file that looks like this:

dependencies:
# renovate: datasource=conda depName=main/sqlalchemy
- sqlalchemy=2.0.34
platforms:
  - linux-64
channels:
  - defaults

If I run conda project add orjson=3.10.7, the resulting file will look like

dependencies:
- sqlalchemy=2.0.34
- orjson=3.10.7
platforms:
  - linux-64
channels:
  - defaults

It stripped the comments. Not only that, but it also doesn't keep the entries sorted like the original file. This is not very convenient.

conda project add should keep the comments and the order as it is.

[AlbertDeFusco]

I see. I'll look into if these comments can be preserved with ruamel.yaml

I think yq might support comments. Maybe a short-term fix for add is to manipulate the yaml with yq then run conda project install --force, which should re-lock since the env file changed
