docker: raise web build V8 heap to 5 GB to match 8 GB host

Browse source 
CT 107 bumped to 8 GB RAM. Capping the heap below the available memory
makes V8 GC-thrash near the limit and contributes to oom-kills. Set
--max-old-space-size to 5120 MB (~60% of host) so the compile has real
headroom while leaving room for kernel + dockerd + buildkit + tsup workers.
