Update outdated description of the synthesizer controls in NVDA's speech settings

[SaschaCowley]

Link to issue number:

None

Summary of the issue:

Section 12.1.2.2, "Change synthesizer" of NVDA's User Guide currently reads:

[...] This button activates the Select Synthesizer dialog, which allows you to select the active speech synthesizer and output device. [...]

Even though output device selection has been moved to NVDA's audio settings.

Description of user facing changes

The outdated reference to changing the audio output device via the speech synthesizer dialog has been removed.

Description of development approach

Removed the words "and output device" from the description of the synthesizer section of the speech page of NVDA's settings in user_docs/en/userGuide.md.

Testing strategy:

Built the user guide and made sure the words were gone and the formatting was still correct.

Known issues with pull request:

None.
