chore(deps-dev): Update trio requirement from <0.34.0,>=0.31.0 to >=0.31.0,<0.35.0

[dependabot]

Updates the requirements on trio to permit the latest version.

Release notes

Sourced from trio's releases.

v0.34.0

Full Changelog: python-trio/trio@v0.33.0...v0.34.0

Features

• MemoryChannelStatistics now has a peak_buffer_used field, which reports the largest number of items that have ever been in the channel's buffer at once. This makes it easier to pick a sensible max_buffer_size based on data from a real run, instead of guessing. (python-trio/trio#1723)
• Support Python 3.15, as of beta 4. Things may still change and so this support may break in the future. (python-trio/trio#3456)

Bugfixes

• Nursery.start() now preserves the __cause__ and __context__ of exceptions raised before task_status.started() is called. (python-trio/trio#3261)
• Fixed incorrect error message in run_process: the stdout pipe check now correctly says "stdout" instead of "stdin". (python-trio/trio#3409)
• Fixed trio.Path.as_uri() on Python 3.14+ to avoid the deprecated pathlib.PurePath.as_uri() path. (python-trio/trio#3460)
• Fixed trio.to_thread.run_sync workers leaking spawner's Context on py314t+ free-threaded builds. (python-trio/trio#3472)

Deprecations and removals

• Trying to use absolute deadlines on a trio.CancelScope constructed with a relative deadline now raises, after being deprecated since Trio 0.27.0.

  To switch a cancel scope from being relative to absolute, replace the trio.CancelScope object instead of trying to mutate it. (python-trio/trio#3403)
