Fix resources links for EGA datasets

[ke4]

The link to EGA dataset resources is broken.

Steps to reproduce:

1. Open an experiment that has a linked EGA dataset resource
2. Go to the Supplementary Information tab
3. Click on the EGA resource

Example dataset: https://wwwdev.ebi.ac.uk/gxa/experiments/E-CURD-146/Supplementary%20Information

Expected result: The browser should open the EGA dataset's page.

Actual result: Page not found

Here are 2 more example datasets that are already on public:

• https://www.ebi.ac.uk/gxa/experiments/E-MTAB-4748/Supplementary%20Information
• https://www.ebi.ac.uk/gxa/experiments/E-MTAB-3983/Supplementary%20Information

The above 2 examples point to EGA studies with EGAS... accessions and using /studies/... in the URL. So the URL looks fine to me, but we got a 404.

• https://www.ebi.ac.uk/ega/studies/EGAS00001000828/
• https://www.ebi.ac.uk/ega/studies/EGAS00001000593/

I asked this last 2 from my EGA contact and waiting for his answer. :crossed_fingers:

The answer was that we have to remove the / from the end of the URL and that should work. :-D

Here is the resource mapping from a previous ticket (#195): accession to resource mappings:

ArrayExpress accessions E-MTAB<> -> ArrayExpress E-ERAD<> -> ArrayExpress E-GEUV<> -> ArrayExpress

Proteome Exchange accessions - can be viewed in PRIDE (and elsewhere) PXD<> -> PRIDE

GEO accessions GSE<> -> GEO GDS<> -> GEO

INSDC consortium project accessions - can be viewed in ENA (and elsewhere) ERP<> -> ENA SRP<> -> ENA DRP<> -> ENA

BioProject NSDC consortium accessions - can be viewed in ENA (and elsewhere) PRJEB<> -> ENA PRJNA<> -> ENA PRJDB<> -> ENA

EGA accessions EGAS<> -> EGA EGAD<> -> EGA

Some E-HCAD experiments (so these would be in SCEA only, not bulk) may have a 'bundle ID' in the secondary accession field in idf but I am not sure if that could be used to search and point to a project in the HCA Data portal
