Version should be a major (min version changed) 5.0.0 (version needs to be bumped)

[mattgoud]

Heads up on the version number before this one goes out.

dev raises ps_versions_compliancy from 1.7.2.0 to 8.2.0, while the last published release, v4.4.3, still declares 1.7.2.0. Shops running PrestaShop 1.7 or 8.0/8.1 can install v4.4.3 today and will no longer be able to install this one, so the release is a breaking change and the table's BC breaks? no does not hold.

The rule agreed for the native modules in the 9.2.0 release preparation is that a raised minimum PrestaShop version means a major bump, whatever else the release contains. ps_banner was the first one out under it, published as v3.0.0 on 08/09, its PR #92 stating Type? improvement and BC breaks? yes (drops support for PrestaShop < 8.2.0 and PHP < 7.1).

So this one would be 5.0.0 rather than 4.4.4, which means:

• $this->version in contactform.php and <version> in config.xml -> 5.0.0
• this PR retitled, Type? improvement and BC breaks? yes
• milestone 4.4.4 (File upload option & no dupplicate message #5) renamed to 5.0.0, keeping its number
• at publication time, the release-drafter draft will propose v4.4.4, since this repo's .github/release-drafter.yml sets tag-template: v$NEXT_PATCH_VERSION, so the tag has to be corrected by hand before publishing

The README is already consistent with 8.2.0, so only the version fields are out of step.

Context: PrestaShop/PrestaShop#41648.

🟢 Approved.

Checked the display of the recipient field on the form, as displayed on the original issue. All good for me.
The rest mainly changes the CI so nothing more needs to be tested here.
