fix: add support for EL10

According to the Ansible team, support for listing platforms in
role `meta/main.yml` files is being removed.
Instead, they recommend using `galaxy_tags`

https://github.com/ansible/ansible/blob/stable-2.17/changelogs/CHANGELOG-v2.17.rst
"Remove the galaxy_info field platforms from the role templates"
ansible/ansible#82453

For each version listed under `platforms.EL` - add a tag like `elN`.

Q: Why not use a delimiter between the platform and the version e.g. `el-10`?

This is not allowed by ansible-lint:

```
meta-no-tags: Tags must contain lowercase letters and digits only., invalid: 'el-10'
meta/main.yml:1
```

So we cannot use uppercase letters either.

Q: Why not use our own meta/main.yml field?

No other fields are allowed by ansible-lint:

```
syntax-check[specific]: 'myfield' is not a valid attribute for a RoleMetadata
```

Q: Why not use some other field?

There are no other applicable or suitable fields.

Q: What happens when we want to support versions like `N.M`?

Use the word "dot" instead of "." e.g. `el10dot3`.
Similarly - use "dash" instead of "-".

We do not need tags such as `fedoraall`.
The `fedora` tag implies that the role works on all supported versions of fedora.
Otherwise, use tags such as `fedora40` if the role only supports specific versions.

In addition - for roles that have different variable files for EL9, create
the corresponding EL10 files, and update the variables for EL10.
