* Remove regression references to non-existant Python versions * Adjust regressions estimated capacity not adjusted by #5389 * Adjusts regression algorithms so that they pass (Index/Index Options) * Changes start/end date on BasicTemplateIndexAlgorithm * Changes option pricing model to BlackScholes in IndexOptionCallITMGreeksExpiryRegressionAlgorithm - The root cause of why there are no greeks at times for these options was identified. It is most likely due to the underlying's VolatilityModel not having had enough data to be "warmed up", which means it will return a standard deviation of zero to the option pricing model, rendering most metrics as NaN. * Adds missing index/index options regression algorithms - Regression algorithms are now 1-1 between C# and Python for Indexes/Index options. All regression tests are now passing * Fixes broken BasicTemplateIndex regression algorithm * Previously traded SPY, but because we have no SPY data in Lean master, I instead opted for index options, since data for those dates is already included * Deal with weekend for breaking test case * Adjust DefaultEndDate test to always pass * Check todays date for open Co-authored-by: Gerardo Salazar <gsalaz9800@gmail.com>

### <summary>

### This regression algorithm tests In The Money (ITM) index option expiry for short calls.
|
|
### We expect 2 orders from the algorithm, which are:
|
|
###
|
|
### * Initial entry, sell SPX Call Option (expiring ITM)
|
|
### * Option assignment
|
|
###
|
|
### Additionally, we test delistings for index options and assert that our
|
|
### portfolio holdings reflect the orders the algorithm has submitted.
