[MINOR][SQL] Spelling: filters - PushedFilers

[jsoref]

What changes were proposed in this pull request?

Consistently correct the spelling of PushedFilters

Why are the changes needed?

@bersprockets noted that it's wrong

Does this PR introduce any user-facing change?

Technically, I think it does. Practically, neither Google nor GitHub show anyone using pushedFilers outside of forks (or the discussion about fixing it started at #30323 (comment))

How was this patch tested?

None beyond CI in the previous PR

Sorry I'm getting to this late - and this is probably an ignorant question, but would this cause any user code to break? like would existing code be setting this under the wrongly-named key at the moment? Just want to make sure we don't break things.

[jsoref]

@srowen: I don't know - nor am I particularly certain about how to check, but apparently the bot is very strongly opinionated.

[srowen]

Ignore the bot, it's just doing housekeeping. That's my only concern - would this break any user code? is this property even observable or settable by users?

[jsoref]

I can't speak definitively, but the most prominent hits are this PR itself or other references to apache/spark internals.

@MaxGekk added this in #29145 in July of 2020, @gengliangwang, @HeartSaVioR, @bersprockets, and @HyukjinKwon seem to be the people most likely to be able to give an educated opinion (and notably, @bersprockets is the one who suggested doing this).

[MaxGekk]

The method getMetaData() is invoke from FileScan.description() and DataSourceV2ScanExecBase.verboseStringWithOperatorId() that print "internal" info about plan nodes. I think that the risk of breaking users apps is low.

@jsoref Could you update PR's description, for instance fill in What changes were proposed in this pull request?.

[jsoref]

@MaxGekk: Done (and the bot seems to hate me)
