release-24.1: ui: index recommendations properly handle quoted table names

[blathers-crl]

Backport 1/1 commits from #121731 on behalf of @abarganier.

/cc @cockroachdb/release

---

Fixes: #119579

Epic: none

The UI code used to modify the index recommendations provided by the
server was not properly accounting for table and column names containing
quotation marks. This was causing invalid CREATE INDEX statements to
be generated, which would fail on request.

This patch fixes this by updating the query modification code to strip
quotation marks from the table name prior to using it to generate an
index name.

Release note (bug fix): Index recommendations in the DB Console will now
function properly for indexes on tables/columns whose names contain
quotation marks and/or whitespace.
For example: CREATE INDEX ON "my table" ("my col");

Release justification: UI bug fix for an easily reproduced bug impacting insights index recommendations.

Thanks for opening a backport.

Please check the backport criteria before merging:

• Backports should only be created for serious
  issues or test-only changes.
• Backports should not break backwards-compatibility.
• Backports should change as little code as possible.
• Backports should not change on-disk formats or node communication protocols.
• Backports should not add new functionality (except as defined
  here).
• Backports must not add, edit, or otherwise modify cluster versions; or add version gates.
• All backports must be reviewed by the owning areas TL and one additional
  TL. For more information as to how that review should be conducted, please consult the backport
  policy.

If your backport adds new functionality, please ensure that the following additional criteria are satisfied:

• There is a high priority need for the functionality that cannot wait until the next release and is difficult to address in another way.
• The new functionality is additive-only and only runs for clusters which have specifically “opted in” to it (e.g. by a cluster setting).
• New code is protected by a conditional check that is trivial to verify and ensures that it only runs for opt-in clusters. State changes must be further protected such that nodes running old binaries will not be negatively impacted by the new state (with a mixed version test added).
• The PM and TL on the team that owns the changed code have signed off that the change obeys the above rules.
• Your backport must be accompanied by a post to the appropriate Slack
  channel (#db-backports-point-releases or #db-backports-XX-X-release) for awareness and discussion.

Also, please add a brief release justification to the body of your PR to justify this
backport.
