fix: po-gettext format issues with CLI

[nakkamarra]

I noticed two issues with the po-gettext format option:

1. The disableSelectWarning flag is not part of the CatalogFormatOptions type, and so it is reported as being invalid by the CLI:

2. The po-gettext format does not properly support the use of lineNumbers format option that the standard po format option supports.

@semoal hey, can I get a quick review on this when you have the chance? Thanks.

@semoal It looks like @iStefo authored the feature, so perhaps he would be able to give a quick review if you are too busy?

Hello Nick, sorry for the delay, had been busy lately with work and Rematch's book.
I'll take a review to everything this weekend and on Tuesday we'll release a version =)
