Richard van der Hoff c885542628 Broaden spec version support (#4014)
This commit does two things:

 * It puts the "minimum supported matrix version" from v1.5 back down to
   v1.1. In other words, it is a partial revert of
   https://github.com/matrix-org/matrix-js-sdk/pull/3970. (Partial, because we
   don't need to update the tests.)

   We're doing this largely because
   https://github.com/matrix-org/matrix-js-sdk/pull/3970 was introduced without
   a suitable announcement and deprecation policy. We haven't yet decided if
   the js-sdk's spec support policy needs to change, or if we will re-introduce
   this change in future in a more graceful manner.

 * It increases the "maximum supported matrix version" from v1.5 up to
   v1.9. Previously, the two concepts were tied together, but as discussed at
   length in
   https://github.com/matrix-org/matrix-js-sdk/issues/3915#issuecomment-1865221366,
   this is incorrect.

   Unfortunately, we have no real way of testing whether it is true that the
   js-sdk actually works with a server which supports *only* v1.9, but as per
   the comment above, we can't do much about that.

Fixes https://github.com/matrix-org/matrix-js-sdk/issues/3915.

* In practice, this means: when we connect to a server, it must declare support for one of the versions in this list.
*
* Note that it does not *necessarily* mean that the js-sdk has good support for all the features in the listed spec
* versions; only that we should be able to provide a base level of functionality with a server that offers support for
