Remove case sensitvity from Scientific Topic, Keyword and other filters

[rombaum]

Describe the bug

I would not expect that a string based search or filter system is case sensitive. Normally, it doesn't matter if you are searching for bioinformatics or Bioinformatics. In TeSS this is currently the case. Which means when I use the value bioinformatics as a filter I did not get any results (see fig. 1). For Bioinformatics I currently get 84 results (see fig. 2). The same behavior also appears for the filter keyword (see fig 3.) or target audience

To Reproduce

Steps to reproduce the behavior:

1. Go to https://tess.elixir-europe.org/materials?scientific_topics=bioinformatics
2. See no records in the result list
3. Go to https://tess.elixir-europe.org/materials?scientific_topics=Bioinformatics
4. See 84 records in the result list

Expected behavior

There should be no difference when selected a filter with uppercase or lowercase letters in it.
