Add control so files are checked out with lf and not crlf.  A number of
tests are shell scripts that run under bash and Windows lineends are not
supported.

npm installs packages differently based on the platform.  The `.bin`
entry the proxy was using is a symlink on UNIX type platforms but may have
three different forms on WIndows.  The actual installed package will
now  be required directly.  This is still a temporary patch pending
fixes for the issues identified in the proxy file.

add documentation for td.replaceEsm API

This test was a stupid idea btw

…mething to do with local paths

…) we still support

The API for `td.replaceEsm` differs a bit in argument interpretation
compared to `td.replace` one, explain it and give documentation reference to
`quibble.esm`.

docs: add testdouble-vitest links to docs

fix: replaceEsm typings

Currently:

```ts
// `subscriptions` is `void`
const subscriptions = await td.replaceEsm(
      '../../subscriptions.js',
);
```

Now:

```ts
// `subscriptions` is `{ [namedExport: string]: any; default?: any; }`
const subscriptions = await td.replaceEsm(
      '../../subscriptions.js',
);
```
