[BUG] Selectable service_description containing spechial character $ produces error

[IceByteZ]

Describe the bug
A selectable service includes a $ in his name, and therefore does not meet the regulations for the regex

NagVis Version
1.9.34

Checkmk Version

2.1.0p32 (CEE)

To Reproduce
Steps to reproduce the behavior:

1. have a db-host with a service named "service_MSSQL$PROD" in checkmk
2. open a nagvis-map and add a new service icon
3. select the db-host as host_name
4. select the service as service_description
5. press "Save"

Expected behavior
An icon for the selected service will be created on the map

Actual behavior
The "add service-icon"-dialogue shows an error message:
The attribute has wrong format (Regex: /^[0-9a-zа-яё\p{L}\s:+[]()_.,'-*?!#@=/\]+$/iu)

Screenshots

Additional information
If there are multiple instances of a MS SQL-Server on an sigle host, Microsoft adds the instancename to the servicenames and splits both using the $ sign. These services are not renameable and will be included into checkmk using the name "service_DB$INSTANCE". The $ sign works inside of checkmk like a charm but seems to disable usage in NagVis.

Finally i searched through all nagvis-files and changed the regex-pattern by myself.
It works for me, but i don't know if it will produce any sideeffects.

File: ./share/nagvis/htdocs/server/core/defines/matches.php
Change the 'MATCH_SERVICE_DESCRIPTION' adding a \$ behind the \*

Perhaps anyone with more knowledge of NagVis can create a mergerequest for this.
