[FIX] theme_cobalt,theme_paptic: enable blog Inter bolder

Scenario:
- install theme_cobalt or theme_paptic
- go to a website blog post
- put a word in bold

Result: the bold is not shown bolder than the text

Issue: Inter font in theme_cobalt and theme_paptic loads weights 400,
600 and 800. The blog post normal font weight is 300 since 2019 (in
odoo/odoo@bb0cdec) and so both normal
font-weight and bold inside it are shown with weight 400 which make bold
not differentiated.

Fix: add 300 weight to Inter font.

Note: in 18.0, Inter font already has weight 300 in theme_odoo_experts,
theme_enark, theme_vehicle, theme_bookstore, theme_nano, theme_clean and
website but it is still missing for cobalt and paptic themes.
