Some printers incorrectly specify the content-type of PDFs as "pdf" instead of
the correct "application/pdf." To handle this situation,
an alias has been introduced, treating content-type "pdf" as "application/pdf."
[Reproducing original bug]
1. run odoo with documents module
2. prepare email file
2.1 create email with a pdf attached
2.2 export email to .eml
2.3 modify content-type of the pdf from "application/pdf" to "pdf"
3. send prepared email to odoo to inbox-financial alias (the default one
creating documents)
4. Go to documents, observe that the created PDF is blank!
[Motivation for fix]
Since:
1. Odoo uses the Python built-in module for parsing emails*
(the actual issue lies outside Odoo code).
2. "pdf" is not an accepted MIME type according to current norms
(https://datatracker.ietf.org/doc/html/rfc6838#section-4.2).
It's not an actual Odoo bug.
However, redirecting this issue to the appropriate printer manufacturer and
waiting for a fix may be time-consuming, hence the proposed fix.
