fix: use an image that supports glibc for @turbo/repository ubuntu (vercel#9845)

### Description

In a [recent
release](https://github.com/vercel/turborepo/actions/runs/13038773591/job/36375503780)
of `@turbo/repository` I noticed that on `x86_64-unknown-linux-gnu` is
failing checkout with:

```text
/__e/node20/bin/node: /lib64/libm.so.6: version `GLIBC_2.27' not found (required by /__e/node20/bin/node)
/__e/node20/bin/node: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /__e/node20/bin/node)
```

### Testing Instructions

#### Verify the old version

```bash
docker pull amazon/aws-lambda-nodejs:18
docker run --rm -it --entrypoint /bin/sh amazon/aws-lambda-nodejs:18
```

then run

```bash
ldd --version
```

To verify that the version was indeed 2.26:

#### Verify the new version

```bash
docker pull node:18-bullseye
docker run --rm -it --entrypoint /bin/sh amazon/aws-lambda-nodejs:20
```

then run

```bash
ldd --version
```

and expect an output like

```
sh-5.2# ldd --version
ldd (GNU libc) 2.34
