SolidBench generates invalid URIs for CSS, causing failed HTTP requests

[constraintAutomaton]

SolidBench is currently generating triple URLs that are not valid in CSS contexts. This leads to HTTP requests that return 404 errors due to improper URL encoding.

For example, the following URL is generated: https://solidbench.linkeddatafragments.org/www.ldbc.eu/ldbc_socialnet/1.0/tag/Anne_Murray_Duets:_Friends_&_Legends

In this case, : in the path should be encoded as %3A for it to work in CSS.
This issue impact the completeness of results because some resources cannot be reach.

The transformation rules that should be applied can be found in the PathUtil.ts file of the CSS.
