Changes to 2 English source files

[Jennifer Hodgdon]

I wanted to let you know that on this issue:
https://www.drupal.org/project/user_guide/issues/3005751
we made a change to the English source file(s) preface-conventions.txt and install-tools.txt :

We added information about Drupal Console as an alternative to Drush, for command-line operations.

Here is the commit for reference:
https://cgit.drupalcode.org/user_guide/commit/?id=0c8eb31

Suggested actions to respond to this change in each language would be either:
a) If the file hasn't been translated yet, copy the English source file to your language directory and commit it.
b) If the file has already been translated, open a new issue to revise the translation.

Thanks!
