Update multi-project workspace link
weblink on the angular.io website was not working, therefore, updated the multi-project workspace link.
PR Close#33166
The `format` attribute is an artifact of an old version of the docs

does anything. People are still copy-pasting it from existing examples.
This commit removes all occurrences of the `format` attribute on code
examples.

1) Path mappings are to be added in the workspace tsconfig files, hence the path needs to be `./` and not `../`
2) Fix export symbol as it cannot contain `-`
