Add sourcemaps to development build

[joluj]

Sourcemaps help debugging, especially when editing the interpreter. The sourcemaps are only emitted when building explicitly with the configuration development. This is enabled by default when running the examples.

Before (References compiled and bundled JS code):

file:///path/to/jayvee/dist/apps/interpreter/main.js:14606
throw new Error("TEST");
      ^

Error: TEST
    at file:///path/to/jayvee/dist/apps/interpreter/main.js:14606:7
    at ModuleJob.run (node:internal/modules/esm/module_job:218:25)
    at async ModuleLoader.import (node:internal/modules/esm/loader:329:24)
    at async loadESM (node:internal/process/esm_loader:34:7)
    at async handleMainPromise (node:internal/modules/run_main:113:12)

After (References TypeScript source):

/path/to/jayvee/libs/interpreter-lib/src/index.ts:10
throw new Error('TEST');
      ^


Error: TEST

    at async ModuleLoader.import (node:internal/modules/esm/loader:329:24)
    at async loadESM (node:internal/process/esm_loader:34:7)

@TungstnBallon FYI, these sourcemaps would have helped you with the runtime error we've talked about on wednesday.
