Uncaught TypeError when i dont run "npm run bootstrap"

when i naively run `npm run build`
then the `common` package fails to build

```sh
cd $(mktemp -d)
git clone --depth 1 https://github.com/dsherret/ts-morph
cd ts-morph/
pnpm import package-lock.json
pnpm install
npm run build
```

```
error: Uncaught TypeError: Cannot read properties of undefined (reading 'getSourceFile')
else if (declarations[0].getSourceFile().isInNodeModules()) {
^

### the right way

> when i naively run `npm run build`

the right way is `npm run bootstrap`

https://github.com/dsherret/ts-morph/blob/f927d01b347b14a667df0334ea974e7133a963d0/DEVELOPMENT.md?plain=1#L1-L8

which is

https://github.com/dsherret/ts-morph/blob/f927d01b347b14a667df0334ea974e7133a963d0/package.json#L7

which also works with `pnpm install`

```
pnpm install
npm run bootstrap
npm run build
```

Reproduce the failure with the commands in the issue, then inspect packages/common/scripts/buildDeclarations.ts around line 23. Compare the direct npm run build path with the documented npm run bootstrap flow in DEVELOPMENT.md and package.json. Done means the build no longer throws the reported TypeError or the required bootstrap step is clearly enforced.
