auto-resolve and add at install groups that are not in the lock file

[deronnax]

Is your feature request related to a problem? Please describe.

When you checkout fresh project managed by pdm, if you run an install commands without specifying a group, it automatically does the resolution locking, including the dev group. So if you do a pdm install and then a pdm install -d later, it works fine.
But then if you want to install with an optional group later (let's say all), you get this error:

$ pdm install -G all
[PdmUsageError]: Requested groups not in lockfile: all

It surprised my coworker and they thought something was broken/wrong with their install or the project.

way to reproduce:

cat <<EOF > pyproject.toml
[project]
dependencies = ["requests"]
requires-python = ">=3.11"

[project.optional-dependencies]
all = ["requests-toolbelt"]

[tool.pdm.dev-dependencies]
dev = ["pytest"]
EOF
pdm install 
pdm install -d
pdm install -G all

Describe the solution you'd like

I would expect PDM to re-do the locking with the optional group when asked to install the optional group, rather than erroring.

You should run pdm add -G all to add and install the dependencies. add is more proper than install since it clearly means to add to the existing groups.
