Typo in the documentation about metadata queries

[sosna]

In the SDMX-REST API, the version parameter defaults to latest (~).

However, for reference metadata queries by metadatasets, it defaults to all (*). This is a typo.

The documentation for providerRef has a few typos as well.

Instead:

• The dot is used as separator between the agency ID and the provider ID, e.g. BIS.CH2;
• In case the dot is missing, e.g. CH2, then it is assumed to be equivalent to *.CH2 (and not all.CH2, as mentioned in the documentation).
• The comma is used as separator between multiple values, e.g. BIS.CH2,BIS.GR2
