Exclude non-native files when extracting localization strings

[fluiddot]

Fixes the case of extra strings of #3466.

Description

I added the following paths to the excluded argument of the make:pot commands, this way we prevent adding extra strings from non-native files.

New excluded paths:

• build/*
• build-module/*
• build-style/*
• *.js
• *.php

In theory, this change shouldn't be required because the --include argument should only include the specified paths, however, this is not working as expected.

Besides, just by excluding *.js should only extract strings from *.native.js files, unfortunately, it's not and it's including by default the build* folders 🤷‍♂️ .

To test

Extra strings are not added

1. Run command npm run genstrings
2. Observe that the localization strings files are not including a high number of strings

Only extract strings from native files

1. Run command npm run makepot:ios -- --debug
2. Observe the output log and verify that only .native.js files are being parsed

Note: Some files are giving parse failures, this is caused by the use of the optional chaining operator that is not supported by the script that extracts the strings.

PR submission checklist:

• I have considered adding unit tests where possible.
• I have considered if this change warrants user-facing release notes more info and have added them to RELEASE-NOTES.txt if necessary.

LGTM. I verified that in this branch npm run genstrings generated significantly fewer translations string changes and npm run makepot:ios -- --debug only included *.native.js files in comparison to the develop branch.
