[TASK] Use new TypoScript location

BREAKING CHANGE! Installing this change will require page templates to be selected anew; until this is done the page's configuration and FE rendering will be broken.

You can bring back the old behaviour using this TypoScript:

```
plugin.tx_fluidpages.collections.fluidpages < plugin.tx_fluidpages.collections.fluidpages_bootstrap
plugin.tx_fluidpages.collections.fluidpages_bootstrap >
```
