Support for pnpm dlx command

[prabhu]

When using the dlx command, our logic to identify the plugins directory isn't working.

❯ corepack pnpm dlx @cyclonedx/cdxgen --help
 WARN  8 deprecated subdependencies found: @npmcli/[email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected]

cdxgen [command]

The below line needs to be enhanced:

cdxgen/lib/managers/binary.js

Line 72 in 47d8e4d

let CDXGEN_PLUGINS_DIR = process.env.CDXGEN_PLUGINS_DIR;

We might need another fix to deal with architecture-specific directories.

The directory naming convention used by dlx is different.

To research:

• Check if dlx command supports a locally created package with pnpm pack.
