Update target profile page UI

[andrewhercules]

To prepare for the upcoming beta launch, can we please make some small adjustments to the target profile page?

• [x] In the cross-reference links section directly under the gene symbol, please change "CRISPR depmap" to "Sanger Cancer DepMap"
• [x] Tractability: fix the fonts when no data is available
• [x] Tractability: when no data is available, please display "No known data"
• [x] Safety: For targets with non-clinical experimental toxicity data (e.g. ABCG2), please update the description to "Details of assays that can be used to test for TARGET_SYMBOL toxicity in vitro", and please add some margin between the description and the data table search bar
• [x] In the "Synonyms" section, if no synonyms are available please display the following string "No synonyms available" - example: NPHP3-ACAD11 (ENSG00000274810)
