feat: include message description in the transifex_input.json file

[OmarIthawi]

Description

developer_message in translations files are useful and provides context for translators in Transifex. However, in most MFEs it's gets discarded.

Bad example: frontend-app-learning

Most repositories provides no developer_message e.g. Learning MFE:

openedx-translations/translations/frontend-app-learning/src/i18n/transifex_input.json

Lines 2 to 6 in e4f68ad

	"learning.accessExpiration.deadline": "Upgrade by {date} to get unlimited access to the course as long as it exists on the site.",
	"learning.accessExpiration.header": "Audit Access Expires {date}",
	"learning.accessExpiration.body": "You lose all access to this course, including your progress, on {date}.",
	"instructorToolbar.pageBanner.courseHasExpired": "This learner no longer has access to this course. Their access expired on {date}.",
	"learning.accessExpiration.upgradeNow": "Upgrade now",

The transifex_input.json is extract with the following command:

• package.json: https://github.com/openedx/frontend-app-learning/blob/81442bebe9af1084e7f01a962cec78f355a4e960/package.json#L14
  "i18n_extract": "BABEL_ENV=i18n fedx-scripts babel src --quiet > /dev/null",

• Makefile: https://github.com/openedx/frontend-app-learning/blob/0bfb817439e71c78f4fd62bc99378f1054d3188f/Makefile#L16-L25

Good example: Paragon

Paragon transifex_input.json includes developer_message which provides helpful context for translators:

openedx-translations/translations/paragon/src/i18n/transifex_input.json

Lines 1 to 13 in 5acf6d6

	{
	"dropzone.Dropzone.invalidSizeLessError": {
	"developer_comment": "A message shown when a file with less than minimum allowed size is being uploaded in Dropzone.",
	"string": "File must be larger than {size}."
	},
	"dropzone.Dropzone.invalidSizeMoreError": {
	"developer_comment": "A message shown when a file with more than maximum allowed size is being uploaded in Dropzone.",
	"string": "File must be less than {size}."
	},
	"dropzone.Dropzone.invalidType": {
	"developer_comment": "A message shown when a file with wrong MIME type is being uploaded.",
	"string": "The file type must be {count, plural, one {{typeString} file} other {one of {typeString} files}}."
	},

Paragon uses the following scripts:

• package.json: https://github.com/openedx/paragon/blob/f7cb7066f92d4bd25dc6dce8681dbf8338987ced/package.json#L39

  "i18n_extract": "formatjs extract 'src/**/*.{jsx,js,tsx,ts}' --out-file ./src/i18n/transifex_input.json --format transifex",

• Makefile: https://github.com/openedx/paragon/blob/ee4daa09521e8cad760c068bbba6314853fa0bd9/Makefile#L33-L37
