[Security] Bump micromatch from 4.0.5 to 4.0.8

Dependabot requested to merge dependabot-npm_and_yarn-micromatch-4.0.8 into master

Bumps micromatch from 4.0.5 to 4.0.8. This update includes a security fix.

Vulnerabilities fixed

Regular Expression Denial of Service (ReDoS) in micromatch The NPM package micromatch is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in micromatch.braces() in index.js because the pattern .* will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.

Patched versions: 4.0.8 Affected versions: < 4.0.8
