v5 URL format: default to first story if no path or storyId is included

[kevinSuttle]

Is your feature request related to a problem? Please describe.
Having to include --* at the end of Storybook URLs is a bit of a task. Seems avoidable.

Describe the solution you'd like

1. If the URL doesn't have --* or $[storyID} at the end of it, the router would redirect to the first story listed.

2. (Maybe related?) If the URL doesn't have

• a /
• or ?
• or path

redirect to the first story

e.g. https://monorepo-git-next.storybook.now.sh/examples/official-storybook - nothing happens
https://monorepo-git-next.storybook.now.sh/examples/official-storybook/ - redirect happens

Describe alternatives you've considered
Always including /, ?, path, and --* at the end of Storybook URLs.

Are you able to assist bring the feature to reality?
I can

Additional context
Example:

https://monorepo-dzdv58z2b.now.sh/examples/official-storybook/?path=/story/docs-docspage--with-subtitle - works

If you remove the --${storyId} at the end, the Story group is selected on the left, but there is no individual story selected or rendered on the Canvas

Try: https://monorepo-dzdv58z2b.now.sh/examples/official-storybook/?path=/story/docs-docspage

@kevinSuttle would also be great if the urls would not be case-sensitive, see #8500

You can find this prerelease on the @next NPM tag.

Closing this issue. Please re-open if you think there's still more to do.
