Update and migrate translating dic/ini files from wiki

[seanbudd]

Summary of the issue:

NV Access is intending to move most of the wiki into the repository, so changes are tracked better and easier to propose.
The documentation for translating NVDA is very dated, particularly since the update of the translation system.

Description of user facing changes

The following pages were already mirrored in the developerGuide.
The developerGuide sections were reviewed and updated.

• Translating Character Descriptions
• Translating Symbols

This wiki page was moved and updated in the developerGuide

• Translating Gestures

The following changes were made to update the contents:

• grammar and formatting fixes
• structure changes to make each section more consistent

Future work

These wiki pages will be removed/deprecated when the updated developerGuide is released in 2024.3
Moving and updating the rest of the translating wiki pages.

Might it be better to create a "Translating guide", to go along with the Developer Guide and User Guide? It seems like there would be enough material.

Here is my review.

Though, I agree with @XLTechie: sooner or later, a separate translation guide would be more than helpful.

If this is part of the developer guide, then in my view it becomes even more relevant to deploy the developer guide via SVN or Crowdin for tranlsation to every language, so #13333 should definitely not cause the developer guide to be removed.
