Otto Bittner 67a58bcc56 docs: rename components to microservices
Since we now have a config value called microserviceVersion
it hopefully makes it easier for users to understand what
this value controls if we also use the term microservice
in the docs.

# Install cert-manager
:::caution
If you want to use cert-manager with Constellation, pay attention to the following to avoid potential pitfalls.
:::
Constellation ships with cert-manager preinstalled.
The default installation is part of the `kube-system` namespace, as all other Constellation-managed microservices.
You are free to install more instances of cert-manager into other namespaces.
However, be aware that any new installation needs to use the same version as the one installed with Constellation or rely on the same CRD versions.
Also remember to set the `installCRDs` value to `false` when installing new cert-manager instances.
It will create problems if you have two installations of cert-manager depending on different versions of the installed CRDs.
CRDs are cluster-wide resources and cert-manager depends on specific versions of those CRDs for each release.
