Inconsistent precision syntax in `/api/v3/write_lp` docs

[suyashcjoshi]

As per slack community thread discussion about InfluxDB 3 Core, there seems to be a doc bug.

This needs investigation and update to the docs page.

/api/v3/write_lp supports abbreviated (ns) or long (nanosecond) units, as well as auto. The supported values list is misleading, omitting the long form.
