Documentation issues / clarification with update instructions

I was following the instructions in this topic to update from mautic 5.0.2 to 5.0.3.

I'm using a composer based installation.

https://docs.mautic.org/en/5.x/getting_started/how_to_update_mautic.html

When running the commands under step 5 of Updating Mautic (composer based installs, I ran into the following issues:

1. Running the second command bin/console mautic:update:apply --finish gives an error "You have composer updates enabled. This means that you can only update Mautic through the 'composer update' command." Should this line be removed then from the documentation?

2. Running bin/console doctrine:schema:update --no-interaction --force I received errors:

   Updating database schema...
   
   In ExceptionConverter.php line 117:
   
   An exception occurred while executing a query: SQLSTATE[42000]: Syntax error or access violation: 1091 Can't DROP 'IDX_1AE3441319EB6921'; check that column/key exists
   
   In Exception.php line 28:

   I'm not sure if those are valid errors, or just because the migrations already applied them in the previous step. In most migration technologies I've used in the past you can make schema and data updates apply in one command. I'm sorry I'm not familiar with doctrine migrations.

Start with the linked Updating Mautic page, especially step 5 for composer-based installs, and reproduce the listed commands if the required environment is available. Verify the composer-update message and the doctrine:schema:update error, then update the instructions so the documented sequence and expected outcomes are clear.
