failures using extra/additional repository with trailing slash

[achubaty]

specifying additional cran-like repo with a trailing slash causes failures when installing packages (ℹ source packages are missing from predictiveecology.r-universe.dev).

> options(repos = c(PE = 'https://predictiveecology.r-universe.dev/'))
> pak::repo_ping()
Repository summary:                                source          
PE            @ predictiveecology.r-universe.dev     x        
CRAN          @ cran.rstudio.com                     ✓      (145ms)
BioCsoft      @ bioconductor.org                     ✓      (346ms)
BioCann       @ bioconductor.org                     ✓      (366ms)
BioCexp       @ bioconductor.org                     ✓      (580ms)
BioCworkflows @ bioconductor.org                     ✓      (449ms)

whereas, removing the trailing slash works:

> options(repos = c(PE = 'https://predictiveecology.r-universe.dev'))
> pak::repo_ping()
Repository summary:                                source

Seems like a bug in the server to me. At least almost all web servers allow double slashes there AFAICT:

I have turned on Normalize URLs to origin in Cloudflare now (under rules > settings). That should fix this problem at least for r-universe.
