[KrasnoshchokBohdan]

• changed 'note' column type from varchar to text, removed length attribute

Description (*)

Error happens here
vendor/magento/framework/Config/Reader/Filesystem.php 186

As the author of the issue noticed, an interesting solution is proposed in
#26155 (comment)

but for now I'll just stick to changing the type, if there are other suggestions I'll be happy to consider them
