feat: Flag indefinite article used before mass nouns (uncountable nouns)

[hippietrail]

Non-native English speakers from all cultures have trouble with mass nouns / uncountable nouns / non-count nouns in English. A little of this may have started to spill over into younger native speakers:

• An advice
• An evidence
• An info/an information
• An infrastructure
• A luggage

Erroneous pluralizations of these seem to all already be flagged by the spellchecker.
Suggestions could include:

• Simply removing the article
• Change a/an into "some"
• Add a quantifier, usually "item of" or "piece of", but some words have one or more idiomatic ones.
• Some of these have one or more other countable nouns with the same meaning that could be suggested: "an advice" -> "a tip", "a suggestion".

A couple of these have become more acceptable in the programming context, so I suppose they should be optional. They sound wrong to people my age and older who are native speakers, but sound fine to non-native speakers and younger native speakers. I'm not sure if it crossed over in or after the Millennial generation:

• I wrote a code → I wrote some code
• This is a software → This is a software package

There are probably word-specific replacements. I'll start a list for each:

code / source code

• an app
• a piece of code
• a program
• a snippet
• a snippet of code
• some code
• code

software

• a piece of software
• an app
• a program
• a software tool
• a software package
• some software
• software
• a tool

"Hardware" may fall into the same category. I'll add it if I find concrete examples in the wild. "Firmware" seems to be different in some way and at least has a plural though "I installed a firmware." still sounds wrong where "They're running different firmwares." sounds more acceptable, possibly not 100% acceptable though.
