build: FORMS-1687 nanoid vulnerability fix

[WalterMoar]

Description

The GitHub Dependabot process has created an alert for the nanoid dependency. To satisfy the requirements outlined in the Security Threat and Risk Assessment's (STRA) Statement of Acceptable Risks (SoAR), this vulnerability must be handled by updating the package version (or mitigated in some other way, if updating the package is not possible).

Notes

• Our package-lock.json is using nanoid v3.3.7
• The nanoid fix version, and latest version, is v3.3.8
• nanoid is a dependency of postcss (^3.3.7)
• Our package-lock.json is using postcss v8.4.49, which is the latest version
• postcss is a dependency of css-loader (^8.4.33)
• Our package.json is using css-loader v7.1.2, which is the latest version

So by doing an update of nanoid we stay within the spec for the postcss dependencies.

Acceptance Criteria

• The nanoid dependency no longer appears in the dependabot's list of packages with vulnerabilities
