[docs] Make Autocomplete docs gender neutral

• I have followed (at least) the PR section of the contributing guide.

Summary

Changed the AutoComplete clearOnBlur API documentation from

If true, the input's text is cleared on blur if no value is selected.Set to true if you want to help the user enter a new value. Set to false if you want to help the user resume his search.

to

If true, the input's text is cleared on blur if no value is selected.Set to true if you want to help the user enter a new value. Set to false if you want to help the user resume their search.

Motivation

The AutoComplete clearOnBlur API documentation fails to recognise that about half the planet/potential users do not identify with he/his pronouns. I figured that this was a small enough change that it would be reasonably simple to fix.

EDIT: I'd like to say thanks for all the work that has gone into the material-ui package and acknowledge that this might well have been a result of unconscious bias. But here is the opportunity to fix that 😄
