Allow array values for meta tags

[BlackWiCKED]

Feature Request

Currently if we want to add multiple og:image tags, the addMeta function overrides the previous values and will use only the last one. According to the Open Graph specs at https://ogp.me/#array it should be possible to define multiple tags with the same property name. SonataSeoBundle is currently not offering this feature as far as I'm aware of, but please correct me if I'm wrong.

CC @core23 Not passing a string seems deprecated since 2.x

SonataSeoBundle/src/Seo/SeoPage.php

Line 142 in dff934e

if (!\is_string($value)) {

Maybe this should be changed before the NEXT_MAJOR

IMHO the method signature for the addMeta is correct. Unfortunately the method does not add any new meta value, it replaces it.

Maybe it just needs a fix here:

SonataSeoBundle/src/Seo/SeoPage.php

Line 154 in dff934e

$this->metas[$type][$name] = [$value, $extras];

Can you do this @BlackWiCKED ?

[BlackWiCKED]

Sure, I can give it a try.
