Core: pycsspeechtts: incorrect language formatting

[PlutonicCloud]

The problem

When using the Microsoft TTS engine with another configuration than the default, Home Assistant returns an error when trying to synthesize:

[pycsspeechtts.pycsspeechtts] Text synthesis failed, statuscode 400, reason:
[homeassistant.components.tts] Error on init TTS: No TTS from microsoft for 'test'

Environment

• Home Assistant Core release with the issue: confirmed on 1.116 and 1.117 (up to 1.117.2)
• Last working Home Assistant Core release (if known): unknown
• Operating environment (OS/Container/Supervised/Core): OS
• Integration causing this issue: TTS / Microsoft / pycsspeechtts
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/microsoft/

Problem-relevant configuration.yaml

tts:
  - platform: microsoft
    api_key: <HIDDEN>
    region: westeurope
    language: nl-nl
    gender: Female
    type: ColetteNeural
    pitch: "default"
    rate: "0"
    volume: "0"
    contour: "(0%,+0%) (100%,+0%)"

Traceback/Error logs

After debugging /usr/local/lib/python3.8/site-packages/pycsspeechtts/pyspeechtts.py I noticed the issue is caused by this line of code:

        voice.set(
            'name', 'Microsoft Server Speech Text to Speech Voice ('+language+', '+voiceType+')')

In the latest version of pyspeechtts.py at https://github.com/jeroenterheerdt/pycsspeechtts, a new function was added and used:

Function to uppercase the country code in the language:

        def name_lang(language):
            lang1,lang2 = language.split("-")
            return "{}-{}".format(lang1,lang2.upper())

Function used:

        voice.set(
            'name', 'Microsoft Server Speech Text to Speech Voice ('+name_lang(language)+', '+voiceType+')')

Applying this to pyspeechtts.py resolves the problem I encountered. TTS is now correctly synthesizing Dutch text using Microsoft Azure TTS.

Additional information

Is it possible to bring the latest version of pycsspeechtts to Home Assistant?

Verified this to be a problem in the dependency, requested new package ^ with @jeroenterheerdt as the issue has already been fixed in the code. Changes as mentioned in the start of this issue do solve the problem.

Just pushed a new package to pypi: https://pypi.org/project/pycsspeechtts/.
