Upgrade scie launder to the latest and pants to 2.17.0.

Trying to use PANTS_DEBUG with command like PANTS_DEBUG=1 pants --no-pantsd export-codegen ::, but having the following error. If I replace the scie launcher with the legacy script, it works fine.

$ PANTS_DEBUG=1 pants --no-pantsd export-codegen ::
Unknown flag --listen on global scope
Did you mean --list-sep, --list-documented, or --isort-version?
Use `pants help` to get help.
Unknown flag --wait-for-client on global scope
Did you mean --test-force?
Use `pants help` to get help.
Exception caught: (pants.option.errors.UnknownFlagsError)

Thanks, when using scie-pants this starts pants with a DAP (debug adaptor protocol) server, waiting for a client to connect before proceeding.

However, there seems to have snuck in a bug in the lift manifest for this boot path:

scie-pants/package/scie-pants.toml

Lines 70 to 80 in 4287b67

# Run Pants Debug Mode
[[lift.commands]]
name = "pants-debug"
# No description because this command shouldn't render in the help output (it's invoked as
# appropriate by the default "Boot" one above)
# description = "Runs a hermetic Pants installation with a debug server for debugging Pants code."
exe = "{scie.bindings.install:VIRTUAL_ENV}/bin/pants"
args = [
"-c",
"""\
sys = __import__("sys")

Those args are for a python interpreter, not directly to pants which will be invoked from the inline script there.. so this seems to be broken.

Good find, thanks :)
