Fix error when viewing source of redacted events (#9914)
* Fix viewing source of redacted events

Clicking 'View Source' in the context menu of a redacted event causes an error,
and the user gets no visible result.

This fixes <ViewSource /> to indicate that the source is unavailable when a
message has been redacted. The original source remains available.

<SyntaxHighlight /> requires a non-null string for its `content` prop, and, in
the case of redacted events, <ViewSource /> was passing `undefined`. This is
ultimately because redacting an event causes `MatrixEvent.clearEvent` to be
`undefined`, which <ViewSource /> wasn't checking.

Fixes https://github.com/vector-im/element-web/issues/24165

* Use correct highlight.js call

Previous call signature was deprecated.
