Display Percentages relative to fastest time

[akhildevelops]

It would be useful to display percentages of execution time of all lang with respect to fastest runtime.

In this page Rust vs Zig: https://programming-language-benchmarks.vercel.app/rust-vs-zig

lang	code	time	time-delay%	stddev	peak-mem	time(user)	time(sys)	compiler/runtime
zig	1.zig	118ms	-	1.1ms	1.0MB	110ms	0ms	zig 0.11.0-dev.3978+711b4e93e
rust	5c-m.rs	185ms	56%	2.2ms	1.7MB	327ms	0ms	rustc 1.73.0-nightly
rust	5-m.rs	204ms	72%	3.5ms	1.8MB	367ms	0ms	rustc 1.70.0
rust	1c.rs	228ms	93%	1.2ms	1.1MB	220ms	0ms	rustc 1.73.0-nightly
rust	1.rs	316ms	167%	1.6ms	1.0MB	297ms	3ms	rustc 1.70.0

All the time values are compared with 118ms
