docs: correct Win11 Creator behavior after the ISO workflow refactor (#4920)

* docs: correct Win11 Creator behavior after the ISO workflow refactor

The creator stopped stripping unused editions, loading offline registry
hives, and running component store cleanup in #4862. It now copies the
ISO contents and applies the selected edition through sources\ei.cfg and
autounattend.xml, leaving install.wim alone unless drivers are injected.

Update the guide and the architecture reference to match, and note that
the output ISO is close to the size of the source.

* docs: align disk space, driver injection, and stuck-run guidance

The disk space block still carried the pre-refactor 10-15 GB workspace,
2.5-3.5 GB output, and ~25 GB total, which contradicted the copy-based
numbers in the data flow. Restate them against the source ISO size.

Driver injection never touches boot.wim. It adds every exported driver
to the selected install.wim index and stages only the storage packages
in $WinpeDriver$ for WinPE, so correct both the guide and the reference.

The stuck-run troubleshooting entry pointed at a WIM dismount that only
happens when driver injection is enabled.

* docs: narrow this PR back to the edition and output size claims

The earlier commits rewrote the surrounding Win11 Creator sections,
which went well beyond what #4918 was about and presented the rest of
the section as reviewed when it had not been.

Restore the untouched text and keep only the claims that promised a
size reduction or edition removal: the strip-editions and component
store bullets, the two data flow lines, and the modified ISO size.
