for consistency, rename ts-x to with-x for the vanilla examples, except for ts -> bare and ts-minimal -> `basic

LGTM. One question I had was the with-solid-router example. Is that a solid start template? Or is that router without start?

[birkskyum]

It's the router without start, just spa routing on the client

I think when this merges the cli can be updated, but this will likely break the references from the cli, so have to happen coordinated - cc @Tommypop2

yeah, I was thinking that too.

The change looks good, but this needs to come together with a CLI release.

Alternatively, we could merge a fallback in the CLI code so both paths work - or even duplicate the templates here and then make another PR deleting once the CLI gets a new release to the updated path.

We can prepare a PR for the cli, so that it can be merged/updated in sync
