Fix Ansible lint in galaxy.yml and meta

[bturmann]

This PR will fix the remaining ansible-lint complains.

Summary:

• minimum allowed version is 1.0.0; use 1.0.0-beta until officially released
• role name can be omitted after migration into collection
• provide minimal changelog (required)
• platform is EL for CentOS and RedHat
• use reasonable recent ansible 2.12 as minimum version
• use only allowed characters for galaxy tags

Tested with: ansible-lint 6.13.1 using ansible 2.14.3

0.0.1 is a correct from a semantic versioning point of view, I'm not sure this is necessary.

[xavierba]

Could you please explain why 2.4 is not high enough ?

i think 2.4 is EOL since a long time, we should probably set the min_ansible_version to ansible-core 2.16

[bturmann]

Ansible-lint complains about 2.4 being outdated, so I tried more recent versions and 2.12 was accepted. The minimum version should be as low as possible. Otherwise, users of conservative / LTS Linux Distributions would be excluded. Example, the current Debian stable 12 Bookworm provides 2.14. 2.12 seems to be  a good compromise to me.

Conservative/stable distributions is what I had in mind. EL7 (still supported for a couple days) has 2.9, Debian 10 has 2.7, Debian 11 has 2.10, Ubuntu 20.04 has 2.9 and Ubuntu 22 has 2.10.
I'll go for 2.7 or 2.9. Granted, both of them are EOL, so the linter will likely not be happy about it, but this is "just" a linter after all :-)

i don't know if it's worth taking care of compatibility with so old version. I guess people who will install LemonLDAP, won't do it on (almost) dead version and we suppor them it will be real pain to maintain / test compatibility with those system.
