Call the language Tala in the API, the documents and the templatesfix/tala-names-in-docs-and-api

The pages were renamed; the rest of the repository still said Visual X#:
- the site API answered with the name Visual X#, and its test expected it;
- the documents, the issue and pull request templates, the support address
  and the name of the code scanning configuration.

The documents also said that a left-to-right mark follows the name of the
language in Hebrew text. That was for the `#` of the old name; the sentence
now speaks of names that end in a symbol, such as C#.

Not changed: host names, paths and unit names on the server, the name of the
backend artifact, the Kotlin package of the backend, and the keys of the
browser storage.
