Update Transifex resources for our documentation

[humitos]

Sync resources from repository (e.g. created/deleted reST doc files) with Transifex configuration.

$ tx config mapping-bulk \
  --project readthedocs-docs \
  --file-extension '.pot' \
  --source-file-dir locale/pot \
  --source-lang en \
  --type PO \
  --expression 'locale/<lang>/LC_MESSAGES/{filepath}/{filename}.po' \
  --execute

After running this command, I searched and replaced _locale_pot_ by `` (none) to respect the pattern that was used for the resources names. The command, ends with a resource name like:

[readthedocs-docs._locale_pot_embed]

which is replaced to

[readthedocs-docs.embed]

If this PR is approved, we need to run the following command to sync the resources into Transifex:

$ tx push --source

I don't fully understand this one. Is this just updating our config to match the existing files, or something more?

[humitos]

Yes.

I added the new (missing) files from our docs into Transifex config by using their tool. Although, since their tool uses a different pattern for naming the resources I did a search and replace to match the pattern that we had previously.

That's all that this PR does. With this new config, we should run tx push --source from docs/ directory so new files are pushed as resources to translate in Transifex.

Sounds good.
