SpeechRecognition does not document all required parameters for the install method

### MDN URL

https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition/install_static

### What specific section or headline is this issue about?

Parameters

### What information was incorrect, unhelpful, or incomplete?

The Parameters section lists only options.langs as a supported parameter. Chrome requires the undocumented processLocally flag be passed as true for install to succeed, and the content in the JS example reflects that by including this parameter.

### What did you expect to see?

[Parameters](https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition/install_static#parameters)
[options](https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition/install_static#options)
An object specifying options for the installation. Possible properties include:

[langs](https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition/install_static#langs)
An array of one or more strings containing [BCP 47 language tags](https://developer.mozilla.org/en-US/docs/Glossary/BCP_47_language_tag), each representing a language that you want to install the language pack for.

[processLoecally](https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition/install_static#processLocally)
A boolean value. The documentation here should explain that this is necessary for the install to succeed. It should also explain the purpose of the function if this is passed as false, which is unclear.
