chore(docs): update docusaurus

[rodsjo]

Type of Work

• Patch: X.Y.Z+1. NEGLIGIBLE visible changes, does not change input or output - OR changes behaviour. Use chore:, refactor: etc
• Minor: X.Y+1.Z. Minor changes, might ADD new input (YAML), or other backwards-compatible changes. Use feat:, fix:
• Major: X+1.Y.Z. Major and most likely BREAKING changes, wo. backwards compatibility, or removing temporary backwards compatibility functionality. Use ! or BREAKING:.

Have you remembered and considered?

• IF FEAT: I have remembered to update documentation
• IF FIX OR FEAT: I have remembered to update manual changelog (docs/drafts/next.draft.md)
• IF BREAKING: I have remembered to update migration guide (docs/docs/migration_guides/)
• IF BREAKING: I have committed with BREAKING: in footer or ! in header
• I have added tests (if not, comment why)
• I have used conventional commits syntax (if you squash, make sure that conventional commit is used)
• I have included the Github issue nr in the footer!

What is this PR all about?

• Updated Docusaurus from 3.9.2 to 3.10.0 (release notes here)
• Since Docusaurus is moving away from proprietary syntax, heading ids had to be changed (link). So I ran the command npx docusaurus write-heading-ids --syntax mdx-comment --migrate to update all heading ids:

-## My Heading {#my-id}
+## My Heading {/* #my-id */}

This changed the old ids' syntax, but also created heading ids for all headings. But I think that is a good thing?

• Overriding a couple of transitive dependencies to fix high and moderate vulnerabilities
  • serialize-javascript version 7.0.5 to fix https://github.com/equinor/ecalc/security/dependabot/59 (overriding the peer dependency is safe link)
  • lodash-es version 4.18.1to fix https://github.com/equinor/ecalc/security/dependabot/62 and https://github.com/equinor/ecalc/security/dependabot/63

What else did you consider?

We should rename all our .md files to .mdx, see documentation here, but this should be done in another PR
