fix(cli): init templates still assume the same versions

[rix0rrr]

The init templates still have a single %cdk-version% placeholder for both the library and the CLI.

Introduce a new %cdk-cli-version% placeholder and fill it with the "current" version of the CLI used to create the template.

Turning DISPLAY_VERSION into a lazy function, because we added a dependency init.ts -> version.ts, and since init.ts is included in a pre-build script, we now include version.ts in that pre-build script which tries to read a file at load time that still needs to be generated.

Tests failed but with the following error, which this PR surely™️ can't have caused:

      npm error code ETARGET
      npm error notarget No matching version found for @babel/generator@^7.26.9.

So I'm confident enough proceeding
