Allow installing canvas 1.10.*

Problem/Motivation

Canvas 1.10.0 and 1.10.1 have been released. canvas_extjs works fine against them, but composer.json still caps the dependency below 1.10, so the module cannot be installed on a 1.10 site.

Steps to reproduce

On a Drupal 11.3+ site:

composer require 'drupal/canvas:1.10.1'
composer require 'drupal/canvas_extjs:^1.2'

The second command fails to resolve:

drupal/canvas_extjs requires drupal/canvas >=1.5 <1.10
  -> found drupal/canvas[1.5.0, ..., 1.9.0] but it conflicts with
     your root composer.json require (1.10.1).

Proposed resolution

Raise the upper bound from 1.10 to 1.11, so the constraint becomes >=1.5 <1.11. This admits all 1.10.x releases while still excluding 1.11 until it has been tested. No code changes are needed.

Follows on from #3614951: Allow installing canvas 1.9.* and #3612009: Allow installing canvas 1.5.* to 1.8.*.
