[CodeQL] Improve MongoDB Output parsing to remove warning about ReDoS

[hasezoey]

Github Severity: High
Actual Severity: Low

I post this issue, because i just dont know enough about Regexes & ReDoS to know how to fix the following:

mongodb-memory-server/packages/mongodb-memory-server-core/src/util/MongoInstance.ts

Lines 574 to 576 in 8e9e560

	if (/lib[\w-.]+(?=: cannot open shared object)/i.test(line)) {
	const lib =
	line.match(/(lib[\w-.]+)(?=: cannot open shared object)/i)?.[1].toLocaleLowerCase() ??

CodeQL message:

This regular expression that depends on library input may run slow on strings starting with 'lib' and with many repetitions of 'lib'.

With 2b733b4 the libsomething.so.1: cannot open shared object CodeQL warning is gone
and with 473c278 the exception in initAndListen CodeQL warning is also gone

so there are no CodeQL / ReDoS warnings anymore with the next version (8.6.1), closing
