Typo : Getting Started -> Configuration -> Grammar Rules

There is a typo in the following link
https://docs.emqx.io/en/broker/v4.3/getting-started/config.html#grammar-rules

> Value types can be integer, fload, percent, enum, ip, string, atom, flag, duration and bytesize

`float` is incorrectly spelled as `fload`.

Open the Getting Started → Configuration → Grammar Rules section at the linked documentation URL and locate the value-types sentence. Correct the spelling of “fload” to “float”, then verify the rendered documentation shows the corrected text.

Written by the indexing model from the issue text.
